+# Code of Conduct
+
+At Pinterest, we work hard to ensure that our work environment is welcoming
+and inclusive to as many people as possible. We are committed to creating this
+environment for everyone involved in our open source projects as well. We
+welcome all participants regardless of ability, age, ethnicity, identified
+gender, religion (or lack there of), sexual orientation and socioeconomic
+status.
+
+This code of conduct details our expectations for upholding these values.
+
+## Good behavior
+
+We expect members of our community to exhibit good behavior including (but of
+course not limited to):
+
+- Using intentional and empathetic language.
+- Focusing on resolving instead of escalating conflict.
+- Providing constructive feedback.
+
+## Unacceptable behavior
+
+Some examples of unacceptable behavior (again, this is not an exhaustive
+list):
+
+- Harassment, publicly or in private.
+- Trolling.
+- Sexual advances (this isn’t the place for it).
+- Publishing other’s personal information.
+- Any behavior which would be deemed unacceptable in a professional environment.
+
+## Recourse
+
+If you are witness to or the target of unacceptable behavior, it should be
+reported to Pinterest at opensource-policy@pinterest.com. All reporters will
+be kept confidential and an appropriate response for each incident will be
+evaluated.
+
+If the maintainers do not uphold and enforce this code of conduct in
+good faith, community leadership will hold them accountable.

+# Code of Conduct
+
+At Pinterest, we work hard to ensure that our work environment is welcoming
+and inclusive to as many people as possible. We are committed to creating this
+environment for everyone involved in our open source projects as well. We
+welcome all participants regardless of ability, age, ethnicity, identified
+gender, religion (or lack there of), sexual orientation and socioeconomic
+status.
+
+This code of conduct details our expectations for upholding these values.
+
+## Good behavior
+
+We expect members of our community to exhibit good behavior including (but of
+course not limited to):
+
+- Using intentional and empathetic language.
+- Focusing on resolving instead of escalating conflict.
+- Providing constructive feedback.
+
+## Unacceptable behavior
+
+Some examples of unacceptable behavior (again, this is not an exhaustive
+list):
+
+- Harassment, publicly or in private.
+- Trolling.
+- Sexual advances (this isn’t the place for it).
+- Publishing other’s personal information.
+- Any behavior which would be deemed unacceptable in a professional environment.
+
+## Recourse
+
+If you are witness to or the target of unacceptable behavior, it should be
+reported to Pinterest at opensource-policy@pinterest.com. All reporters will
+be kept confidential and an appropriate response for each incident will be
+evaluated.
+
+If the maintainers do not uphold and enforce this code of conduct in
+good faith, community leadership will hold them accountable.

+# Code of Conduct
+
+At Pinterest, we work hard to ensure that our work environment is welcoming
+and inclusive to as many people as possible. We are committed to creating this
+environment for everyone involved in our open source projects as well. We
+welcome all participants regardless of ability, age, ethnicity, identified
+gender, religion (or lack there of), sexual orientation and socioeconomic
+status.
+
+This code of conduct details our expectations for upholding these values.
+
+## Good behavior
+
+We expect members of our community to exhibit good behavior including (but of
+course not limited to):
+
+- Using intentional and empathetic language.
+- Focusing on resolving instead of escalating conflict.
+- Providing constructive feedback.
+
+## Unacceptable behavior
+
+Some examples of unacceptable behavior (again, this is not an exhaustive
+list):
+
+- Harassment, publicly or in private.
+- Trolling.
+- Sexual advances (this isn’t the place for it).
+- Publishing other’s personal information.
+- Any behavior which would be deemed unacceptable in a professional environment.
+
+## Recourse
+
+If you are witness to or the target of unacceptable behavior, it should be
+reported to Pinterest at opensource-policy@pinterest.com. All reporters will
+be kept confidential and an appropriate response for each incident will be
+evaluated.
+
+If the maintainers do not uphold and enforce this code of conduct in
+good faith, community leadership will hold them accountable.

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the

+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+
+## Fast, non-deadlocking parallel object cache for iOS and OS X.
+
+[PINCache](Source/PINCache.h) is a fork of [TMCache](https://github.com/tumblr/TMCache) re-architected to fix issues with deadlocking caused by heavy use. It is a key/value store designed for persisting temporary objects that are expensive to reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar stores, one in memory ([PINMemoryCache](Source/PINMemoryCache.h)) and one on disk ([PINDiskCache](Source/PINDiskCache.h)), all backed by GCD and safe to access from multiple threads simultaneously. On iOS, `PINMemoryCache` will clear itself when the app receives a memory warning or goes into the background. Objects stored in `PINDiskCache` remain until you trim the cache yourself, either manually or by setting a byte or age limit.
+
+`PINCache` and `PINDiskCache` accept any object conforming to [NSCoding](https://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Protocols/NSCoding_Protocol/Reference/Reference.html). Put things in like this:
+
+**Objective-C**
+```objective-c
+UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]];
+[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately
+```
+**Swift**
+```swift
+let img = UIImage(data: data, scale:UIScreen.main.scale)
+PINCache.shared().setObject(img, forKey: "img")
+```
+
+Get them back out like this:
+
+**Objective-C**
+```objc
+[[PINCache sharedCache] objectForKeyAsync:@"image" block:^(PINCache *cache, NSString *key, id object) {
+    UIImage *image = (UIImage *)object;
+    NSLog(@"image scale: %f", image.scale);
+}];
+```
+**Swift**
+```swift
+PINCache.shared().object(forKey: "image") { (cache, key, object) in
+    if let image = object as? UIImage {
+        print("image scale: %f", image.scale)
+    }
+}
+```
+
+Both `PINMemoryCache` and `PINDiskCache` use locks to protect reads and writes. `PINCache` coordinates them so that objects added to memory are available immediately to other threads while being written to disk safely in the background. Both caches are public properties of `PINCache`, so it's easy to manipulate one or the other separately if necessary.
+
+Collections work too. Thanks to the magic of `NSKeyedArchiver`, objects repeated in a collection only occupy the space of one on disk:
+
+**Objective-C**
+```objective-c
+NSArray *images = @[ image, image, image ];
+[[PINCache sharedCache] setObject:images forKey:@"images"];
+NSLog(@"3 for the price of 1: %d", [[[PINCache sharedCache] diskCache] byteCount]);
+```
+**Swift**
+```swift
+// In Swift, Array, String, and Dictionary are all value types.
+let images = [image, image, image] as NSArray // Cast to NSArray
+PINCache.shared.setObject(images, forKey: "images")
+print("3 for the prices of 1: %d", PINCache.shared.diskCache.byteCount)
+```
+
+## Installation
+
+### Manually
+
+[Download the latest tag](https://github.com/pinterest/PINCache/tags) and drag the `PINCache` folder into your Xcode project.
+
+Install the docs by double clicking the `.docset` file under `docs/`, or view them online at [cocoadocs.org](http://cocoadocs.org/docsets/PINCache/)
+
+### Git Submodule
+
+    git submodule add https://github.com/pinterest/PINCache.git
+    git submodule update --init
+
+### CocoaPods
+
+Add [PINCache](http://cocoapods.org/?q=name%3APINCache) to your `Podfile` and run `pod install`.
+
+### Carthage
+
+Add the following line to your `Cartfile` and run `carthage update --platform ios`. Then follow [this instruction of Carthage](https://github.com/carthage/carthage#adding-frameworks-to-unit-tests-or-a-framework) to embed the framework.

+# Release Process
+This document describes the process for a public PINCache release.
+
+### Preparation
+- Install [github_changelog_generator](https://github.com/skywinder/Github-Changelog-Generator): `sudo gem install github_changelog_generator`
+- Generate a GitHub Personal Access Token to prevent running into public GitHub API rate limits: https://github.com/github-changelog-generator/github-changelog-generator#github-token
+
+### Process
+- Run `github_changelog_generator` in PINCache project directory: `github_changelog_generator --token <generated personal token> --user Pinterest --project PINCache`. To avoid hitting rate limit, the generator will replace the entire file with just the changes from this version – revert that giant deletion to get the entire new changelog.
+- Update `spec.version` within `PINCache.podspec` and the `since-tag` and `future-release` fields in `.github_changelog_generator`.
+- Create a new PR with the updated `PINCache.podspec` and the newly generated changelog, add `#changelog` to the PR message so the CI will not prevent merging it.
+- After merging in the PR, [create a new GitHub release](https://github.com/Pinterest/PINCache/releases/new). Use the generated changelog for the new release.
+- Push to Cocoapods with `pod trunk push`

+/**
+ `PINCache` is a thread safe key/value store designed for persisting temporary objects that are expensive to
+ reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar
+ stores, one in memory (<PINMemoryCache>) and one on disk (<PINDiskCache>).
+ 
+ `PINCache` itself actually does very little; its main function is providing a front end for a common use case:
+ a small, fast memory cache that asynchronously persists itself to a large, slow disk cache. When objects are
+ removed from the memory cache in response to an "apocalyptic" event they remain in the disk cache and are
+ repopulated in memory the next time they are accessed. `PINCache` also does the tedious work of creating a
+ dispatch group to wait for both caches to finish their operations without blocking each other.
+ 
+ The parallel caches are accessible as public properties (<memoryCache> and <diskCache>) and can be manipulated
+ separately if necessary. See the docs for <PINMemoryCache> and <PINDiskCache> for more details.
+
+ @warning when using in extension or watch extension, define PIN_APP_EXTENSIONS=1

+/**
+ `PINDiskCache` is a thread safe key/value store backed by the file system. It accepts any object conforming
+ to the `NSCoding` protocol, which includes the basic Foundation data types and collection classes and also
+ many UIKit classes, notably `UIImage`. All work is performed on a serial queue shared by all instances in
+ the app, and archiving is handled by `NSKeyedArchiver`. This is a particular advantage for `UIImage` because
+ it skips `UIImagePNGRepresentation()` and retains information like scale and orientation.
+ 
+ The designated initializer for `PINDiskCache` is <initWithName:>. The <name> string is used to create a directory
+ under Library/Caches that scopes disk access for this instance. Multiple instances with the same name are *not* 
+ allowed as they would conflict with each other.
+ 
+ Unless otherwise noted, all properties and methods are safe to access from any thread at any time. All blocks
+ will cause the queue to wait, making it safe to access and manipulate the actual cache files on disk for the
+ duration of the block.
+ 
+ Because this cache is bound by disk I/O it can be much slower than <PINMemoryCache>, although values stored in
+ `PINDiskCache` persist after application relaunch. Using <PINCache> is recommended over using `PINDiskCache`
+ by itself, as it adds a fast layer of additional memory caching while still writing to disk.
+
+ All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an optional
+ <ageLimit> will trigger a GCD timer to periodically to trim the cache with <trimToDate:>.

+/**
+ `PINMemoryCache` is a fast, thread safe key/value store similar to `NSCache`. On iOS it will clear itself
+ automatically to reduce memory usage when the app receives a memory warning or goes into the background.
+ 
+ Access is natively synchronous. Asynchronous variations are provided. Every asynchronous method accepts a
+ callback block that runs on a concurrent <concurrentQueue>, with cache reads and writes protected by a lock.
+ 
+ All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an
+ optional <ageLimit> will trigger a GCD timer to periodically to trim the cache to that age.
+ 
+ Objects can optionally be set with a "cost", which could be a byte count or any other meaningful integer.
+ Setting a <costLimit> will automatically keep the cache below that value with <trimToCostByEvictionStrategy:>.
+ 
+ Values will not persist after application relaunch or returning from the background. See <PINCache> for
+ a memory cache backed by a disk cache.

+# Code of Conduct
+
+At Pinterest, we work hard to ensure that our work environment is welcoming
+and inclusive to as many people as possible. We are committed to creating this
+environment for everyone involved in our open source projects as well. We
+welcome all participants regardless of ability, age, ethnicity, identified
+gender, religion (or lack there of), sexual orientation and socioeconomic
+status.
+
+This code of conduct details our expectations for upholding these values.
+
+## Good behavior
+
+We expect members of our community to exhibit good behavior including (but of
+course not limited to):
+
+- Using intentional and empathetic language.
+- Focusing on resolving instead of escalating conflict.
+- Providing constructive feedback.
+
+## Unacceptable behavior
+
+Some examples of unacceptable behavior (again, this is not an exhaustive
+list):
+
+- Harassment, publicly or in private.
+- Trolling.
+- Sexual advances (this isn’t the place for it).
+- Publishing other’s personal information.
+- Any behavior which would be deemed unacceptable in a professional environment.
+
+## Recourse
+
+If you are witness to or the target of unacceptable behavior, it should be
+reported to Pinterest at opensource-policy@pinterest.com. All reporters will
+be kept confidential and an appropriate response for each incident will be
+evaluated.
+
+If the maintainers do not uphold and enforce this code of conduct in
+good faith, community leadership will hold them accountable.

-/**
- `PINCache` is a thread safe key/value store designed for persisting temporary objects that are expensive to
- reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar
- stores, one in memory (<PINMemoryCache>) and one on disk (<PINDiskCache>).
- 
- `PINCache` itself actually does very little; its main function is providing a front end for a common use case:
- a small, fast memory cache that asynchronously persists itself to a large, slow disk cache. When objects are
- removed from the memory cache in response to an "apocalyptic" event they remain in the disk cache and are
- repopulated in memory the next time they are accessed. `PINCache` also does the tedious work of creating a
- dispatch group to wait for both caches to finish their operations without blocking each other.
- 
- The parallel caches are accessible as public properties (<memoryCache> and <diskCache>) and can be manipulated
- separately if necessary. See the docs for <PINMemoryCache> and <PINDiskCache> for more details.
-
- @warning when using in extension or watch extension, define PIN_APP_EXTENSIONS=1

-/**
- `PINDiskCache` is a thread safe key/value store backed by the file system. It accepts any object conforming
- to the `NSCoding` protocol, which includes the basic Foundation data types and collection classes and also
- many UIKit classes, notably `UIImage`. All work is performed on a serial queue shared by all instances in
- the app, and archiving is handled by `NSKeyedArchiver`. This is a particular advantage for `UIImage` because
- it skips `UIImagePNGRepresentation()` and retains information like scale and orientation.
- 
- The designated initializer for `PINDiskCache` is <initWithName:>. The <name> string is used to create a directory
- under Library/Caches that scopes disk access for this instance. Multiple instances with the same name are *not* 
- allowed as they would conflict with each other.
- 
- Unless otherwise noted, all properties and methods are safe to access from any thread at any time. All blocks
- will cause the queue to wait, making it safe to access and manipulate the actual cache files on disk for the
- duration of the block.
- 
- Because this cache is bound by disk I/O it can be much slower than <PINMemoryCache>, although values stored in
- `PINDiskCache` persist after application relaunch. Using <PINCache> is recommended over using `PINDiskCache`
- by itself, as it adds a fast layer of additional memory caching while still writing to disk.
-
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an optional
- <ageLimit> will trigger a GCD timer to periodically to trim the cache with <trimToDate:>.

-/**
- `PINMemoryCache` is a fast, thread safe key/value store similar to `NSCache`. On iOS it will clear itself
- automatically to reduce memory usage when the app receives a memory warning or goes into the background.
- 
- Access is natively synchronous. Asynchronous variations are provided. Every asynchronous method accepts a
- callback block that runs on a concurrent <concurrentQueue>, with cache reads and writes protected by an semaphore.
- 
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an
- optional <ageLimit> will trigger a GCD timer to periodically to trim the cache to that age.
- 
- Objects can optionally be set with a "cost", which could be a byte count or any other meaningful integer.
- Setting a <costLimit> will automatically keep the cache below that value with <trimToCostByDate:>.
- 
- Values will not persist after application relaunch or returning from the background. See <PINCache> for
- a memory cache backed by a disk cache.

-## Fast, non-deadlocking parallel object cache for iOS and OS X.
-
-[PINCache](PINCache/PINCache.h) is a fork of [TMCache](https://github.com/tumblr/TMCache) re-architected to fix issues with deadlocking caused by heavy use. It is a key/value store designed for persisting temporary objects that are expensive to reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar stores, one in memory ([PINMemoryCache](PINCache/PINMemoryCache.h)) and one on disk ([PINDiskCache](PINCache/PINDiskCache.h)), all backed by GCD and safe to access from multiple threads simultaneously. On iOS, `PINMemoryCache` will clear itself when the app receives a memory warning or goes into the background. Objects stored in `PINDiskCache` remain until you trim the cache yourself, either manually or by setting a byte or age limit.
-
-`PINCache` and `PINDiskCache` accept any object conforming to [NSCoding](https://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Protocols/NSCoding_Protocol/Reference/Reference.html). Put things in like this:
-
-```objective-c
-UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]];
-[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately
-```
-
-Get them back out like this:
-
-```objective-c
-[[PINCache sharedCache] objectForKey:@"image"
-                              block:^(PINCache *cache, NSString *key, id object) {
-                                  UIImage *image = (UIImage *)object;
-                                  NSLog(@"image scale: %f", image.scale);
-                              }];
-```
-
-Both `PINMemoryCache` and PINDiskCache use locks to protect reads and writes. `PINCache` coordinates them so that objects added to memory are available immediately to other threads while being written to disk safely in the background. Both caches are public properties of `PINCache`, so it's easy to manipulate one or the other separately if necessary.
-
-Collections work too. Thanks to the magic of `NSKeyedArchiver`, objects repeated in a collection only occupy the space of one on disk:
-
-```objective-c
-NSArray *images = @[ image, image, image ];
-[[PINCache sharedCache] setObject:images forKey:@"images"];
-NSLog(@"3 for the price of 1: %d", [[[PINCache sharedCache] diskCache] byteCount]);
-```
-
-## Installation
-
-### Manually
-
-[Download the latest tag](https://github.com/pinterest/PINCache/tags) and drag the `PINCache` folder into your Xcode project.
-

-
-### Git Submodule
-
-    git submodule add https://github.com/pinterest/PINCache.git
-    git submodule update --init
-
-### CocoaPods
-
-Add [PINCache](http://cocoapods.org/?q=name%3APINCache) to your `Podfile` and run `pod install`.
-
-### Carthage
-
-Add the following line to your `Cartfile` and run `carthage update --platform ios`. Then follow [this instruction of Carthage](https://github.com/carthage/carthage#adding-frameworks-to-unit-tests-or-a-framework) to embed the framework.

-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,
-   publicly display, publicly perform, sublicense, and distribute the
-   Work and such Derivative Works in Source or Object form.

-   (except as stated in this section) patent license to make, have made,
-   use, offer to sell, sell, import, and otherwise transfer the Work,
-   where such license applies only to those patent claims licensable
-   by such Contributor that are necessarily infringed by their

-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:

-       that You distribute, all copyright, patent, trademark, and
-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside
-       or as an addendum to the NOTICE text from the Work, provided
-       that such additional attribution notices cannot be construed
-       as modifying the License.
-
-   You may add Your own copyright statement to Your modifications and
-   may provide additional or different license terms and conditions
-   for use, reproduction, or distribution of Your modifications, or
-   for any such Derivative Works as a whole, provided Your use,

-   any Contribution intentionally submitted for inclusion in the Work
-   by You to the Licensor shall be under the terms and conditions of

-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,
-   unless required by applicable law (such as deliberate and grossly
-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-
-Description:
-============
-
-WebP codec: library to encode and decode images in WebP format. This package
-contains the library that can be used in other programs to add WebP support,
-as well as the command line tools 'cwebp' and 'dwebp'.
-
-See http://developers.google.com/speed/webp
-
-The latest source tree is available at
-https://chromium.googlesource.com/webm/libwebp
-
-It is released under the same license as the WebM project.
-See http://www.webmproject.org/license/software/ or the
-file "COPYING" file for details. An additional intellectual
-property rights grant can be found in the file PATENTS.
-
-Building:
-=========
-
-Windows build:
---------------
-
-By running:
-
-  nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output
-
-the directory output\release-static\(x64|x86)\bin will contain the tools
-cwebp.exe and dwebp.exe. The directory output\release-static\(x64|x86)\lib will
-contain the libwebp static library.
-The target architecture (x86/x64) is detected by Makefile.vc from the Visual
-Studio compiler (cl.exe) available in the system path.
-
-Unix build using makefile.unix:
--------------------------------
-
-On platforms with GNU tools installed (gcc and make), running
-
-  make -f makefile.unix
-
-will build the binaries examples/cwebp and examples/dwebp, along
-with the static library src/libwebp.a. No system-wide installation
-is supplied, as this is a simple alternative to the full installation
-system based on the autoconf tools (see below).
-Please refer to makefile.unix for additional details and customizations.
-
-Using autoconf tools:
----------------------
-Prerequisites:
-A compiler (e.g., gcc), make, autoconf, automake, libtool.
-On a Debian-like system the following should install everything you need for a
-minimal build:
-$ sudo apt-get install gcc make autoconf automake libtool
-
-When building from git sources, you will need to run autogen.sh to generate the
-configure script.
-
-./configure
-make
-make install
-
-should be all you need to have the following files
-
-/usr/local/include/webp/decode.h
-/usr/local/include/webp/encode.h
-/usr/local/include/webp/types.h
-/usr/local/lib/libwebp.*
-/usr/local/bin/cwebp
-/usr/local/bin/dwebp
-
-installed.
-
-Note: A decode-only library, libwebpdecoder, is available using the
-'--enable-libwebpdecoder' flag. The encode library is built separately and can
-be installed independently using a minor modification in the corresponding
-Makefile.am configure files (see comments there). See './configure --help' for
-more options.
-
-SWIG bindings:
---------------
-
-To generate language bindings from swig/libwebp.swig at least swig-1.3
-(http://www.swig.org) is required.
-
-Currently the following functions are mapped:
-Decode:
-  WebPGetDecoderVersion
-  WebPGetInfo
-  WebPDecodeRGBA
-  WebPDecodeARGB
-  WebPDecodeBGRA
-  WebPDecodeBGR
-  WebPDecodeRGB
-
-Encode:
-  WebPGetEncoderVersion
-  WebPEncodeRGBA
-  WebPEncodeBGRA
-  WebPEncodeRGB
-  WebPEncodeBGR
-  WebPEncodeLosslessRGBA
-  WebPEncodeLosslessBGRA
-  WebPEncodeLosslessRGB
-  WebPEncodeLosslessBGR
-
-See swig/README for more detailed build instructions.
-
-Java bindings:
-
-To build the swig-generated JNI wrapper code at least JDK-1.5 (or equivalent)
-is necessary for enum support. The output is intended to be a shared object /
-DLL that can be loaded via System.loadLibrary("webp_jni").
-
-Python bindings:
-
-To build the swig-generated Python extension code at least Python 2.6 is
-required. Python < 2.6 may build with some minor changes to libwebp.swig or the
-generated code, but is untested.
-
-Encoding tool:
-==============
-
-The examples/ directory contains tools for encoding (cwebp) and
-decoding (dwebp) images.
-
-The easiest use should look like:
-  cwebp input.png -q 80 -o output.webp
-which will convert the input file to a WebP file using a quality factor of 80
-on a 0->100 scale (0 being the lowest quality, 100 being the best. Default
-value is 75).
-You might want to try the -lossless flag too, which will compress the source
-(in RGBA format) without any loss. The -q quality parameter will in this case
-control the amount of processing time spent trying to make the output file as
-small as possible.
-
-A longer list of options is available using the -longhelp command line flag:
-
-> cwebp -longhelp
-Usage:
- cwebp [-preset <...>] [options] in_file [-o out_file]
-
-If input size (-s) for an image is not specified, it is
-assumed to be a PNG, JPEG, TIFF or WebP file.
-
-Options:
-  -h / -help  ............ short help
-  -H / -longhelp  ........ long help
-  -q <float> ............. quality factor (0:small..100:big)
-  -alpha_q <int> ......... transparency-compression quality (0..100)
-  -preset <string> ....... preset setting, one of:
-                            default, photo, picture,
-                            drawing, icon, text
-     -preset must come first, as it overwrites other parameters
-  -z <int> ............... activates lossless preset with given
-                           level in [0:fast, ..., 9:slowest]
-
-  -m <int> ............... compression method (0=fast, 6=slowest)
-  -segments <int> ........ number of segments to use (1..4)
-  -size <int> ............ target size (in bytes)
-  -psnr <float> .......... target PSNR (in dB. typically: 42)
-
-  -s <int> <int> ......... input size (width x height) for YUV
-  -sns <int> ............. spatial noise shaping (0:off, 100:max)
-  -f <int> ............... filter strength (0=off..100)
-  -sharpness <int> ....... filter sharpness (0:most .. 7:least sharp)
-  -strong ................ use strong filter instead of simple (default)
-  -nostrong .............. use simple filter instead of strong
-  -partition_limit <int> . limit quality to fit the 512k limit on
-                           the first partition (0=no degradation ... 100=full)
-  -pass <int> ............ analysis pass number (1..10)
-  -crop <x> <y> <w> <h> .. crop picture with the given rectangle
-  -resize <w> <h> ........ resize picture (after any cropping)
-  -mt .................... use multi-threading if available
-  -low_memory ............ reduce memory usage (slower encoding)
-  -map <int> ............. print map of extra info
-  -print_psnr ............ prints averaged PSNR distortion
-  -print_ssim ............ prints averaged SSIM distortion
-  -print_lsim ............ prints local-similarity distortion
-  -d <file.pgm> .......... dump the compressed output (PGM file)
-  -alpha_method <int> .... transparency-compression method (0..1)
-  -alpha_filter <string> . predictive filtering for alpha plane,
-                           one of: none, fast (default) or best
-  -exact ................. preserve RGB values in transparent area
-  -blend_alpha <hex> ..... blend colors against background color
-                           expressed as RGB values written in
-                           hexadecimal, e.g. 0xc0e0d0 for red=0xc0
-                           green=0xe0 and blue=0xd0
-  -noalpha ............... discard any transparency information
-  -lossless .............. encode image losslessly
-  -near_lossless <int> ... use near-lossless image
-                           preprocessing (0..100=off)
-  -hint <string> ......... specify image characteristics hint,
-                           one of: photo, picture or graph
-
-  -metadata <string> ..... comma separated list of metadata to
-                           copy from the input to the output if present.
-                           Valid values: all, none (default), exif, icc, xmp
-
-  -short ................. condense printed message
-  -quiet ................. don't print anything
-  -version ............... print version number and exit
-  -noasm ................. disable all assembly optimizations
-  -v ..................... verbose, e.g. print encoding/decoding times
-  -progress .............. report encoding progress
-
-Experimental Options:
-  -jpeg_like ............. roughly match expected JPEG size
-  -af .................... auto-adjust filter strength
-  -pre <int> ............. pre-processing filter
-
-The main options you might want to try in order to further tune the
-visual quality are:
- -preset
- -sns
- -f
- -m
-
-Namely:
-  * 'preset' will set up a default encoding configuration targeting a
-     particular type of input. It should appear first in the list of options,
-     so that subsequent options can take effect on top of this preset.
-     Default value is 'default'.
-  * 'sns' will progressively turn on (when going from 0 to 100) some additional
-     visual optimizations (like: segmentation map re-enforcement). This option
-     will balance the bit allocation differently. It tries to take bits from the
-     "easy" parts of the picture and use them in the "difficult" ones instead.
-     Usually, raising the sns value (at fixed -q value) leads to larger files,
-     but with better quality.
-     Typical value is around '75'.
-  * 'f' option directly links to the filtering strength used by the codec's
-     in-loop processing. The higher the value, the smoother the
-     highly-compressed area will look. This is particularly useful when aiming
-     at very small files. Typical values are around 20-30. Note that using the
-     option -strong/-nostrong will change the type of filtering. Use "-f 0" to
-     turn filtering off.
-  * 'm' controls the trade-off between encoding speed and quality. Default is 4.
-     You can try -m 5 or -m 6 to explore more (time-consuming) encoding
-     possibilities. A lower value will result in faster encoding at the expense
-     of quality.
-
-Decoding tool:
-==============
-
-There is a decoding sample in examples/dwebp.c which will take
-a .webp file and decode it to a PNG image file (amongst other formats).
-This is simply to demonstrate the use of the API. You can verify the
-file test.webp decodes to exactly the same as test_ref.ppm by using:
-
- cd examples
- ./dwebp test.webp -ppm -o test.ppm
- diff test.ppm test_ref.ppm
-
-The full list of options is available using -h:
-
-> dwebp -h
-Usage: dwebp in_file [options] [-o out_file]
-
-Decodes the WebP image file to PNG format [Default]
-Use following options to convert into alternate image formats:
-  -pam ......... save the raw RGBA samples as a color PAM
-  -ppm ......... save the raw RGB samples as a color PPM
-  -bmp ......... save as uncompressed BMP format
-  -tiff ........ save as uncompressed TIFF format
-  -pgm ......... save the raw YUV samples as a grayscale PGM
-                 file with IMC4 layout
-  -yuv ......... save the raw YUV samples in flat layout
-
- Other options are:
-  -version  .... print version number and exit
-  -nofancy ..... don't use the fancy YUV420 upscaler
-  -nofilter .... disable in-loop filtering
-  -nodither .... disable dithering
-  -dither <d> .. dithering strength (in 0..100)
-  -alpha_dither  use alpha-plane dithering if needed
-  -mt .......... use multi-threading
-  -crop <x> <y> <w> <h> ... crop output with the given rectangle
-  -resize <w> <h> ......... scale the output (*after* any cropping)
-  -flip ........ flip the output vertically
-  -alpha ....... only save the alpha plane
-  -incremental . use incremental decoding (useful for tests)
-  -h     ....... this help message
-  -v     ....... verbose (e.g. print encoding/decoding times)
-  -quiet ....... quiet mode, don't print anything
-  -noasm ....... disable all assembly optimizations
-
-Visualization tool:
-===================
-
-There's a little self-serve visualization tool called 'vwebp' under the
-examples/ directory. It uses OpenGL to open a simple drawing window and show
-a decoded WebP file. It's not yet integrated in the automake build system, but
-you can try to manually compile it using the recommendations below.

-
-Encoding API:
-=============
-
-The main encoding functions are available in the header src/webp/encode.h
-The ready-to-use ones are:
-size_t WebPEncodeRGB(const uint8_t* rgb, int width, int height, int stride,
-                     float quality_factor, uint8_t** output);
-size_t WebPEncodeBGR(const uint8_t* bgr, int width, int height, int stride,
-                     float quality_factor, uint8_t** output);
-size_t WebPEncodeRGBA(const uint8_t* rgba, int width, int height, int stride,
-                      float quality_factor, uint8_t** output);
-size_t WebPEncodeBGRA(const uint8_t* bgra, int width, int height, int stride,
-                      float quality_factor, uint8_t** output);
-
-They will convert raw RGB samples to a WebP data. The only control supplied
-is the quality factor.
-
-There are some variants for using the lossless format:
-
-size_t WebPEncodeLosslessRGB(const uint8_t* rgb, int width, int height,
-                             int stride, uint8_t** output);
-size_t WebPEncodeLosslessBGR(const uint8_t* bgr, int width, int height,
-                             int stride, uint8_t** output);
-size_t WebPEncodeLosslessRGBA(const uint8_t* rgba, int width, int height,
-                              int stride, uint8_t** output);
-size_t WebPEncodeLosslessBGRA(const uint8_t* bgra, int width, int height,
-                              int stride, uint8_t** output);
-
-Of course in this case, no quality factor is needed since the compression
-occurs without loss of the input values, at the expense of larger output sizes.
-
-Advanced encoding API:
-----------------------
-
-A more advanced API is based on the WebPConfig and WebPPicture structures.
-
-WebPConfig contains the encoding settings and is not tied to a particular
-picture.
-WebPPicture contains input data, on which some WebPConfig will be used for
-compression.
-The encoding flow looks like:
-
--------------------------------------- BEGIN PSEUDO EXAMPLE
-
-#include <webp/encode.h>
-
-  // Setup a config, starting form a preset and tuning some additional
-  // parameters
-  WebPConfig config;
-  if (!WebPConfigPreset(&config, WEBP_PRESET_PHOTO, quality_factor))
-    return 0;   // version error
-  }
-  // ... additional tuning
-  config.sns_strength = 90;
-  config.filter_sharpness = 6;
-  config_error = WebPValidateConfig(&config);  // not mandatory, but useful
-
-  // Setup the input data
-  WebPPicture pic;
-  if (!WebPPictureInit(&pic)) {
-    return 0;  // version error
-  }
-  pic.width = width;
-  pic.height = height;
-  // allocated picture of dimension width x height
-  if (!WebPPictureAllocate(&pic)) {
-    return 0;   // memory error
-  }
-  // at this point, 'pic' has been initialized as a container,
-  // and can receive the Y/U/V samples.
-  // Alternatively, one could use ready-made import functions like
-  // WebPPictureImportRGB(), which will take care of memory allocation.
-  // In any case, past this point, one will have to call
-  // WebPPictureFree(&pic) to reclaim memory.
-
-  // Set up a byte-output write method. WebPMemoryWriter, for instance.
-  WebPMemoryWriter wrt;
-  WebPMemoryWriterInit(&wrt);     // initialize 'wrt'
-
-  pic.writer = MyFileWriter;
-  pic.custom_ptr = my_opaque_structure_to_make_MyFileWriter_work;
-
-  // Compress!
-  int ok = WebPEncode(&config, &pic);   // ok = 0 => error occurred!
-  WebPPictureFree(&pic);  // must be called independently of the 'ok' result.
-
-  // output data should have been handled by the writer at that point.
-  // -> compressed data is the memory buffer described by wrt.mem / wrt.size
-
-  // deallocate the memory used by compressed data
-  WebPMemoryWriterClear(&wrt);
-
--------------------------------------- END PSEUDO EXAMPLE
-
-Decoding API:
-=============
-
-This is mainly just one function to call:
-
-#include "webp/decode.h"
-uint8_t* WebPDecodeRGB(const uint8_t* data, size_t data_size,
-                       int* width, int* height);
-
-Please have a look at the file src/webp/decode.h for the details.
-There are variants for decoding in BGR/RGBA/ARGB/BGRA order, along with
-decoding to raw Y'CbCr samples. One can also decode the image directly into a
-pre-allocated buffer.
-
-To detect a WebP file and gather the picture's dimensions, the function:
-  int WebPGetInfo(const uint8_t* data, size_t data_size,
-                  int* width, int* height);
-is supplied. No decoding is involved when using it.
-
-Incremental decoding API:
-=========================
-
-In the case when data is being progressively transmitted, pictures can still
-be incrementally decoded using a slightly more complicated API. Decoder state
-is stored into an instance of the WebPIDecoder object. This object can be
-created with the purpose of decoding either RGB or Y'CbCr samples.
-For instance:
-
-  WebPDecBuffer buffer;
-  WebPInitDecBuffer(&buffer);
-  buffer.colorspace = MODE_BGR;
-  ...
-  WebPIDecoder* idec = WebPINewDecoder(&buffer);
-
-As data is made progressively available, this incremental-decoder object
-can be used to decode the picture further. There are two (mutually exclusive)
-ways to pass freshly arrived data:
-
-either by appending the fresh bytes:
-
-  WebPIAppend(idec, fresh_data, size_of_fresh_data);
-
-or by just mentioning the new size of the transmitted data:
-
-  WebPIUpdate(idec, buffer, size_of_transmitted_buffer);
-
-Note that 'buffer' can be modified between each call to WebPIUpdate, in
-particular when the buffer is resized to accommodate larger data.
-
-These functions will return the decoding status: either VP8_STATUS_SUSPENDED if
-decoding is not finished yet or VP8_STATUS_OK when decoding is done. Any other
-status is an error condition.
-
-The 'idec' object must always be released (even upon an error condition) by
-calling: WebPDelete(idec).
-
-To retrieve partially decoded picture samples, one must use the corresponding
-method: WebPIDecGetRGB or WebPIDecGetYUVA.
-It will return the last displayable pixel row.
-
-Lastly, note that decoding can also be performed into a pre-allocated pixel
-buffer. This buffer must be passed when creating a WebPIDecoder, calling
-WebPINewRGB() or WebPINewYUVA().
-
-Please have a look at the src/webp/decode.h header for further details.
-
-Advanced Decoding API:
-======================
-
-WebP decoding supports an advanced API which provides on-the-fly cropping and
-rescaling, something of great usefulness on memory-constrained environments like
-mobile phones. Basically, the memory usage will scale with the output's size,
-not the input's, when one only needs a quick preview or a zoomed in portion of
-an otherwise too-large picture. Some CPU can be saved too, incidentally.
-
--------------------------------------- BEGIN PSEUDO EXAMPLE
-     // A) Init a configuration object
-     WebPDecoderConfig config;
-     CHECK(WebPInitDecoderConfig(&config));
-
-     // B) optional: retrieve the bitstream's features.
-     CHECK(WebPGetFeatures(data, data_size, &config.input) == VP8_STATUS_OK);
-
-     // C) Adjust 'config' options, if needed
-     config.options.no_fancy_upsampling = 1;

-     config.options.scaled_height = scaledHeight();
-     // etc.
-
-     // D) Specify 'config' output options for specifying output colorspace.
-     // Optionally the external image decode buffer can also be specified.
-     config.output.colorspace = MODE_BGRA;
-     // Optionally, the config.output can be pointed to an external buffer as
-     // well for decoding the image. This externally supplied memory buffer
-     // should be big enough to store the decoded picture.
-     config.output.u.RGBA.rgba = (uint8_t*) memory_buffer;
-     config.output.u.RGBA.stride = scanline_stride;
-     config.output.u.RGBA.size = total_size_of_the_memory_buffer;
-     config.output.is_external_memory = 1;
-
-     // E) Decode the WebP image. There are two variants w.r.t decoding image.
-     // The first one (E.1) decodes the full image and the second one (E.2) is
-     // used to incrementally decode the image using small input buffers.
-     // Any one of these steps can be used to decode the WebP image.
-
-     // E.1) Decode full image.
-     CHECK(WebPDecode(data, data_size, &config) == VP8_STATUS_OK);
-
-     // E.2) Decode image incrementally.
-     WebPIDecoder* const idec = WebPIDecode(NULL, NULL, &config);

-       if (status == VP8_STATUS_OK || status == VP8_STATUS_SUSPENDED) {
-         bytes_remaining -= bytes_read;
-       } else {
-         break;
-       }
-     }
-     WebPIDelete(idec);
-
-     // F) Decoded image is now in config.output (and config.output.u.RGBA).
-     // It can be saved, displayed or otherwise processed.
-
-     // G) Reclaim memory allocated in config's object. It's safe to call
-     // this function even if the memory is external and wasn't allocated

-
-Note: The nature of EXIF, XMP and ICC data is not checked and is assumed to be
-valid.
-
-Visualization tool:
-===================
-
-The examples/ directory also contains a tool (vwebp) for viewing WebP files.
-It decodes the image and visualizes it using OpenGL. See the libwebp README
-for details on building and running this program.
-
-Mux API:
-========
-The Mux API contains methods for adding data to and reading data from WebP
-files. This API currently supports XMP/EXIF metadata, ICC profile and animation.
-Other features may be added in subsequent releases.
-
-Example#1 (pseudo code): Creating a WebPMux object with image data, color
-profile and XMP metadata.
-
-  int copy_data = 0;
-  WebPMux* mux = WebPMuxNew();
-  // ... (Prepare image data).

-
-Demux API:
-==========
-The Demux API enables extraction of images and extended format data from
-WebP files. This API currently supports reading of XMP/EXIF metadata, ICC
-profile and animated images. Other features may be added in subsequent
-releases.
-
-Code example: Demuxing WebP data to extract all the frames, ICC profile
-and EXIF/XMP metadata.
-
-  WebPDemuxer* demux = WebPDemux(&webp_data);
-  uint32_t width = WebPDemuxGetI(demux, WEBP_FF_CANVAS_WIDTH);
-  uint32_t height = WebPDemuxGetI(demux, WEBP_FF_CANVAS_HEIGHT);
-  // ... (Get information about the features present in the WebP file).
-  uint32_t flags = WebPDemuxGetI(demux, WEBP_FF_FORMAT_FLAGS);
-
-  // ... (Iterate over all frames).
-  WebPIterator iter;
-  if (WebPDemuxGetFrame(demux, 1, &iter)) {
-    do {
-      // ... (Consume 'iter'; e.g. Decode 'iter.fragment' with WebPDecode(),
-      // ... and get other frame properties like width, height, offsets etc.
-      // ... see 'struct WebPIterator' below for more info).
-    } while (WebPDemuxNextFrame(&iter));
-    WebPDemuxReleaseIterator(&iter);
-  }
-
-  // ... (Extract metadata).
-  WebPChunkIterator chunk_iter;
-  if (flags & ICCP_FLAG) WebPDemuxGetChunk(demux, "ICCP", 1, &chunk_iter);
-  // ... (Consume the ICC profile in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  if (flags & EXIF_FLAG) WebPDemuxGetChunk(demux, "EXIF", 1, &chunk_iter);
-  // ... (Consume the EXIF metadata in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  if (flags & XMP_FLAG) WebPDemuxGetChunk(demux, "XMP ", 1, &chunk_iter);
-  // ... (Consume the XMP metadata in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  WebPDemuxDelete(demux);
-
-
-For a detailed Demux API reference, please refer to the header file
-(src/webp/demux.h).
-
-AnimEncoder API:
-================
-The AnimEncoder API can be used to create animated WebP images.
-
-Code example:
-
-  WebPAnimEncoderOptions enc_options;
-  WebPAnimEncoderOptionsInit(&enc_options);
-  // ... (Tune 'enc_options' as needed).
-  WebPAnimEncoder* enc = WebPAnimEncoderNew(width, height, &enc_options);
-  while(<there are more frames>) {
-    WebPConfig config;
-    WebPConfigInit(&config);
-    // ... (Tune 'config' as needed).
-    WebPAnimEncoderAdd(enc, frame, duration, &config);
-  }
-  WebPAnimEncoderAssemble(enc, webp_data);
-  WebPAnimEncoderDelete(enc);
-  // ... (Write the 'webp_data' to a file, or re-mux it further).
-
-
-For a detailed AnimEncoder API reference, please refer to the header file
-(src/webp/mux.h).

-// inline YUV<->RGB conversion function
-//
-// The exact naming is Y'CbCr, following the ITU-R BT.601 standard.
-// More information at: http://en.wikipedia.org/wiki/YCbCr
-// Y = 0.2569 * R + 0.5044 * G + 0.0979 * B + 16
-// U = -0.1483 * R - 0.2911 * G + 0.4394 * B + 128
-// V = 0.4394 * R - 0.3679 * G - 0.0715 * B + 128
-// We use 16bit fixed point operations for RGB->YUV conversion (YUV_FIX).
-//
-// For the Y'CbCr to RGB conversion, the BT.601 specification reads:
-//   R = 1.164 * (Y-16) + 1.596 * (V-128)
-//   G = 1.164 * (Y-16) - 0.813 * (V-128) - 0.391 * (U-128)
-//   B = 1.164 * (Y-16)                   + 2.018 * (U-128)
-// where Y is in the [16,235] range, and U/V in the [16,240] range.
-//
-// The fixed-point implementation used here is:
-//  R = (19077 . y             + 26149 . v - 14234) >> 6
-//  G = (19077 . y -  6419 . u - 13320 . v +  8708) >> 6
-//  B = (19077 . y + 33050 . u             - 17685) >> 6
-// where the '.' operator is the mulhi_epu16 variant:
-//   a . b = ((a << 8) * b) >> 16
-// that preserves 8 bits of fractional precision before final descaling.

-// Encodes the given alpha data via specified compression method 'method'.
-// The pre-processing (quantization) is performed if 'quality' is less than 100.
-// For such cases, the encoding is lossy. The valid range is [0, 100] for
-// 'quality' and [0, 1] for 'method':
-//   'method = 0' - No compression;
-//   'method = 1' - Use lossless coder on the alpha plane only
-// 'filter' values [0, 4] correspond to prediction modes none, horizontal,
-// vertical & gradient filters. The prediction mode 4 will try all the
-// prediction modes 0 to 3 and pick the best one.
-// 'effort_level': specifies how much effort must be spent to try and reduce
-//  the compressed output size. In range 0 (quick) to 6 (slow).
-//
-// 'output' corresponds to the buffer containing compressed alpha data.
-//          This buffer is allocated by this method and caller should call
-//          WebPSafeFree(*output) when done.
-// 'output_size' corresponds to size of this compressed alpha buffer.
-//
-// Returns 1 on successfully encoding the alpha and
-//         0 if either:
-//           invalid quality or method, or
-//           memory allocation for the compressed data fails.

-/**
- `PINCache` is a thread safe key/value store designed for persisting temporary objects that are expensive to
- reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar
- stores, one in memory (<PINMemoryCache>) and one on disk (<PINDiskCache>).
- 
- `PINCache` itself actually does very little; its main function is providing a front end for a common use case:
- a small, fast memory cache that asynchronously persists itself to a large, slow disk cache. When objects are
- removed from the memory cache in response to an "apocalyptic" event they remain in the disk cache and are
- repopulated in memory the next time they are accessed. `PINCache` also does the tedious work of creating a
- dispatch group to wait for both caches to finish their operations without blocking each other.
- 
- The parallel caches are accessible as public properties (<memoryCache> and <diskCache>) and can be manipulated
- separately if necessary. See the docs for <PINMemoryCache> and <PINDiskCache> for more details.

-/**
- `PINDiskCache` is a thread safe key/value store backed by the file system. It accepts any object conforming
- to the `NSCoding` protocol, which includes the basic Foundation data types and collection classes and also
- many UIKit classes, notably `UIImage`. All work is performed on a serial queue shared by all instances in
- the app, and archiving is handled by `NSKeyedArchiver`. This is a particular advantage for `UIImage` because
- it skips `UIImagePNGRepresentation()` and retains information like scale and orientation.
- 
- The designated initializer for `PINDiskCache` is <initWithName:>. The <name> string is used to create a directory
- under Library/Caches that scopes disk access for this instance. Multiple instances with the same name are *not* 
- allowed as they would conflict with each other.
- 
- Unless otherwise noted, all properties and methods are safe to access from any thread at any time. All blocks
- will cause the queue to wait, making it safe to access and manipulate the actual cache files on disk for the
- duration of the block.
- 
- Because this cache is bound by disk I/O it can be much slower than <PINMemoryCache>, although values stored in
- `PINDiskCache` persist after application relaunch. Using <PINCache> is recommended over using `PINDiskCache`
- by itself, as it adds a fast layer of additional memory caching while still writing to disk.
-
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an optional
- <ageLimit> will trigger a GCD timer to periodically to trim the cache with <trimToDate:>.

-/**
- `PINMemoryCache` is a fast, thread safe key/value store similar to `NSCache`. On iOS it will clear itself
- automatically to reduce memory usage when the app receives a memory warning or goes into the background.
- 
- Access is natively synchronous. Asynchronous variations are provided. Every asynchronous method accepts a
- callback block that runs on a concurrent <concurrentQueue>, with cache reads and writes protected by an semaphore.
- 
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an
- optional <ageLimit> will trigger a GCD timer to periodically to trim the cache to that age.
- 
- Objects can optionally be set with a "cost", which could be a byte count or any other meaningful integer.
- Setting a <costLimit> will automatically keep the cache below that value with <trimToCostByDate:>.
- 
- Values will not persist after application relaunch or returning from the background. See <PINCache> for
- a memory cache backed by a disk cache.

- - Accessing an object in the cache does not extend that object's lifetime in the cache
- - When attempting to access an object in the cache that has lived longer than self.ageLimit,
- the cache will behave as if the object does not exist

-## Fast, non-deadlocking parallel object cache for iOS and OS X.
-
-[PINCache](PINCache/PINCache.h) is a fork of [TMCache](https://github.com/tumblr/TMCache) re-architected to fix issues with deadlocking caused by heavy use. It is a key/value store designed for persisting temporary objects that are expensive to reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar stores, one in memory ([PINMemoryCache](PINCache/PINMemoryCache.h)) and one on disk ([PINDiskCache](PINCache/PINDiskCache.h)), all backed by GCD and safe to access from multiple threads simultaneously. On iOS, `PINMemoryCache` will clear itself when the app receives a memory warning or goes into the background. Objects stored in `PINDiskCache` remain until you trim the cache yourself, either manually or by setting a byte or age limit.
-
-`PINCache` and `PINDiskCache` accept any object conforming to [NSCoding](https://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Protocols/NSCoding_Protocol/Reference/Reference.html). Put things in like this:
-
-```objective-c
-UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]];
-[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately
-```
-
-Get them back out like this:
-
-```objective-c
-[[PINCache sharedCache] objectForKey:@"image"
-                              block:^(PINCache *cache, NSString *key, id object) {
-                                  UIImage *image = (UIImage *)object;
-                                  NSLog(@"image scale: %f", image.scale);
-                              }];
-```
-
-Both `PINMemoryCache` and PINDiskCache use locks to protect reads and writes. `PINCache` coordinates them so that objects added to memory are available immediately to other threads while being written to disk safely in the background. Both caches are public properties of `PINCache`, so it's easy to manipulate one or the other separately if necessary.
-
-Collections work too. Thanks to the magic of `NSKeyedArchiver`, objects repeated in a collection only occupy the space of one on disk:
-
-```objective-c
-NSArray *images = @[ image, image, image ];
-[[PINCache sharedCache] setObject:images forKey:@"images"];
-NSLog(@"3 for the price of 1: %d", [[[PINCache sharedCache] diskCache] byteCount]);
-```
-
-## Installation
-
-### Manually
-
-[Download the latest tag](https://github.com/pinterest/PINCache/tags) and drag the `PINCache` folder into your Xcode project.
-
-Install the docs by double clicking the `.docset` file under `docs/`, or view them online at [cocoadocs.org](http://cocoadocs.org/docsets/PINCache/)
-
-### Git Submodule
-
-    git submodule add https://github.com/pinterest/PINCache.git
-    git submodule update --init
-
-### CocoaPods
-
-Add [PINCache](http://cocoapods.org/?q=name%3APINCache) to your `Podfile` and run `pod install`.
-
-### Carthage
-
-Add the following line to your `Cartfile` and run `carthage update --platform ios`. Then follow [this instruction of Carthage](https://github.com/carthage/carthage#adding-frameworks-to-unit-tests-or-a-framework) to embed the framework.

-   this License, each Contributor hereby grants to You a perpetual,
-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,
-   publicly display, publicly perform, sublicense, and distribute the
-   Work and such Derivative Works in Source or Object form.
-

-   (except as stated in this section) patent license to make, have made,
-   use, offer to sell, sell, import, and otherwise transfer the Work,

-   with the Work to which such Contribution(s) was submitted. If You
-   institute patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-

-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or
-       Derivative Works a copy of this License; and

-   (c) You must retain, in the Source form of any Derivative Works
-       that You distribute, all copyright, patent, trademark, and
-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside
-       or as an addendum to the NOTICE text from the Work, provided
-       that such additional attribution notices cannot be construed
-       as modifying the License.
-
-   You may add Your own copyright statement to Your modifications and
-   may provide additional or different license terms and conditions
-   for use, reproduction, or distribution of Your modifications, or
-   for any such Derivative Works as a whole, provided Your use,
-   reproduction, and distribution of the Work otherwise complies with
-   the conditions stated in this License.
-
-5. Submission of Contributions. Unless You explicitly state otherwise,
-   any Contribution intentionally submitted for inclusion in the Work
-   by You to the Licensor shall be under the terms and conditions of
-   this License, without any additional terms or conditions.
-   Notwithstanding the above, nothing herein shall supersede or modify
-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,
-   unless required by applicable law (such as deliberate and grossly
-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-FLAnimatedImage is a performant animated GIF engine for iOS:
-
-- Plays multiple GIFs simultaneously with a playback speed comparable to desktop browsers
-- Honors variable frame delays
-- Behaves gracefully under memory pressure
-- Eliminates delays or blocking during the first playback loop
-- Interprets the frame delays of fast GIFs the same way modern browsers do
-
-It's a well-tested [component that powers all GIFs in Flipboard](http://engineering.flipboard.com/2014/05/animated-gif/). To understand its behavior it comes with an interactive demo:
-
-![Flipboard playing multiple GIFs](https://github.com/Flipboard/FLAnimatedImage/raw/master/images/flanimatedimage-demo-player.gif)
-
-## Who is this for?
-
-- Apps that don't support animated GIFs yet
-- Apps that already support animated GIFs but want a higher performance solution
-- People who want to tinker with the code ([the corresponding blog post](http://engineering.flipboard.com/2014/05/animated-gif/) is a great place to start; also see the *To Do* section below)
-
-## Installation & Usage
-
-FLAnimatedImage is a well encapsulated drop-in component. Simply replace your `UIImageView` instances with instances of `FLAnimatedImageView` to get animated GIF support. There is no central cache or state to manage.
-
-If using CocoaPods, the quickest way to try it out is to type this on the command line:
-
-```shell
-$ pod try FLAnimatedImage
-```
-
-To add it to your app, copy the two classes `FLAnimatedImage.h/.m` and `FLAnimatedImageView.h/.m` into your Xcode project or add via [CocoaPods](http://cocoapods.org) by adding this to your Podfile:
-
-```ruby
-pod 'FLAnimatedImage', '~> 1.0'
-```
-
-If using [Carthage](https://github.com/Carthage/Carthage), add following line into your `Cartfile`
-
-```
-github "Flipboard/FLAnimatedImage"
-```
-
-In your code, `#import "FLAnimatedImage.h"`, create an image from an animated GIF, and setup the image view to display it:
-
-```objective-c
-FLAnimatedImage *image = [FLAnimatedImage animatedImageWithGIFData:[NSData dataWithContentsOfURL:[NSURL URLWithString:@"https://upload.wikimedia.org/wikipedia/commons/2/2c/Rotating_earth_%28large%29.gif"]]];
-FLAnimatedImageView *imageView = [[FLAnimatedImageView alloc] init];
-imageView.animatedImage = image;
-imageView.frame = CGRectMake(0.0, 0.0, 100.0, 100.0);
-[self.view addSubview:imageView];
-```
-
-It's flexible to integrate in your custom image loading stack and backwards compatible to iOS 6.
-
-It uses ARC and the Apple frameworks `QuartzCore`, `ImageIO`, `MobileCoreServices`, and `CoreGraphics`.
-
-It is capable of fine-grained logging. A block can be set on `FLAnimatedImage` that's invoked when logging occurs with various log levels via the `+setLogBlock:logLevel:` method. For example:
-
-```objective-c
-// Set up FLAnimatedImage logging.
-[FLAnimatedImage setLogBlock:^(NSString *logString, FLLogLevel logLevel) {
-    // Using NSLog
-    NSLog(@"%@", logString);
-    
-    // ...or CocoaLumberjackLogger only logging warnings and errors
-    if (logLevel == FLLogLevelError) {
-        DDLogError(@"%@", logString);
-    } else if (logLevel == FLLogLevelWarn) {
-        DDLogWarn(@"%@", logString);
-    }
-} logLevel:FLLogLevelWarn];
-```
-
-Since FLAnimatedImage is licensed under MIT, it's compatible with the terms of using it for any app on the App Store.
-
-## To Do
-- Support other animated image formats such as APNG or WebP (WebP support implemented [here](https://github.com/Flipboard/FLAnimatedImage/pull/86))
-- Integration into network libraries and image caches
-- Investigate whether `FLAnimatedImage` should become a `UIImage` subclass
-- Smarter buffering
-- Bring demo app to iPhone
-
-This has successfully shipped to many people as is, but please do come with your questions, issues and pull requests!

-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,

-   with the Work to which such Contribution(s) was submitted. If You
-   institute patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-

-   Work or Derivative Works thereof in any medium, with or without
-   modifications, and in Source or Object form, provided that You
-   meet the following conditions:
-
-   (a) You must give any other recipients of the Work or
-       Derivative Works a copy of this License; and

-   (c) You must retain, in the Source form of any Derivative Works
-       that You distribute, all copyright, patent, trademark, and
-       attribution notices from the Source form of the Work,
-       excluding those notices that do not pertain to any part of
-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside
-       or as an addendum to the NOTICE text from the Work, provided
-       that such additional attribution notices cannot be construed
-       as modifying the License.
-
-   You may add Your own copyright statement to Your modifications and
-   may provide additional or different license terms and conditions

-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,

-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.
-
-9. Accepting Warranty or Additional Liability. While redistributing
-   the Work or Derivative Works thereof, You may choose to offer,
-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-/**
- `PINCache` is a thread safe key/value store designed for persisting temporary objects that are expensive to
- reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar
- stores, one in memory (<PINMemoryCache>) and one on disk (<PINDiskCache>).
- 
- `PINCache` itself actually does very little; its main function is providing a front end for a common use case:
- a small, fast memory cache that asynchronously persists itself to a large, slow disk cache. When objects are
- removed from the memory cache in response to an "apocalyptic" event they remain in the disk cache and are
- repopulated in memory the next time they are accessed. `PINCache` also does the tedious work of creating a
- dispatch group to wait for both caches to finish their operations without blocking each other.
- 
- The parallel caches are accessible as public properties (<memoryCache> and <diskCache>) and can be manipulated
- separately if necessary. See the docs for <PINMemoryCache> and <PINDiskCache> for more details.
-
- @warning when using in extension or watch extension, define PIN_APP_EXTENSIONS=1

-/**
- `PINDiskCache` is a thread safe key/value store backed by the file system. It accepts any object conforming
- to the `NSCoding` protocol, which includes the basic Foundation data types and collection classes and also
- many UIKit classes, notably `UIImage`. All work is performed on a serial queue shared by all instances in
- the app, and archiving is handled by `NSKeyedArchiver`. This is a particular advantage for `UIImage` because
- it skips `UIImagePNGRepresentation()` and retains information like scale and orientation.
- 
- The designated initializer for `PINDiskCache` is <initWithName:>. The <name> string is used to create a directory
- under Library/Caches that scopes disk access for this instance. Multiple instances with the same name are *not* 
- allowed as they would conflict with each other.
- 
- Unless otherwise noted, all properties and methods are safe to access from any thread at any time. All blocks
- will cause the queue to wait, making it safe to access and manipulate the actual cache files on disk for the
- duration of the block.
- 
- Because this cache is bound by disk I/O it can be much slower than <PINMemoryCache>, although values stored in
- `PINDiskCache` persist after application relaunch. Using <PINCache> is recommended over using `PINDiskCache`
- by itself, as it adds a fast layer of additional memory caching while still writing to disk.
-
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an optional
- <ageLimit> will trigger a GCD timer to periodically to trim the cache with <trimToDate:>.

- `PINMemoryCache` is a fast, thread safe key/value store similar to `NSCache`. On iOS it will clear itself
- automatically to reduce memory usage when the app receives a memory warning or goes into the background.
- 
- Access is natively synchronous. Asynchronous variations are provided. Every asynchronous method accepts a
- callback block that runs on a concurrent <concurrentQueue>, with cache reads and writes protected by an semaphore.
- 
- All access to the cache is dated so the that the least-used objects can be trimmed first. Setting an
- optional <ageLimit> will trigger a GCD timer to periodically to trim the cache to that age.
- 
- Objects can optionally be set with a "cost", which could be a byte count or any other meaningful integer.
- Setting a <costLimit> will automatically keep the cache below that value with <trimToCostByDate:>.
- 
- Values will not persist after application relaunch or returning from the background. See <PINCache> for
- a memory cache backed by a disk cache.

-## Fast, non-deadlocking parallel object cache for iOS and OS X.
-
-[PINCache](PINCache/PINCache.h) is a fork of [TMCache](https://github.com/tumblr/TMCache) re-architected to fix issues with deadlocking caused by heavy use. It is a key/value store designed for persisting temporary objects that are expensive to reproduce, such as downloaded data or the results of slow processing. It is comprised of two self-similar stores, one in memory ([PINMemoryCache](PINCache/PINMemoryCache.h)) and one on disk ([PINDiskCache](PINCache/PINDiskCache.h)), all backed by GCD and safe to access from multiple threads simultaneously. On iOS, `PINMemoryCache` will clear itself when the app receives a memory warning or goes into the background. Objects stored in `PINDiskCache` remain until you trim the cache yourself, either manually or by setting a byte or age limit.
-
-`PINCache` and `PINDiskCache` accept any object conforming to [NSCoding](https://developer.apple.com/library/ios/#documentation/Cocoa/Reference/Foundation/Protocols/NSCoding_Protocol/Reference/Reference.html). Put things in like this:
-
-```objective-c
-UIImage *img = [[UIImage alloc] initWithData:data scale:[[UIScreen mainScreen] scale]];
-[[PINCache sharedCache] setObject:img forKey:@"image" block:nil]; // returns immediately
-```
-
-Get them back out like this:
-
-```objective-c
-[[PINCache sharedCache] objectForKey:@"image"
-                              block:^(PINCache *cache, NSString *key, id object) {
-                                  UIImage *image = (UIImage *)object;
-                                  NSLog(@"image scale: %f", image.scale);
-                              }];
-```
-
-Both `PINMemoryCache` and PINDiskCache use locks to protect reads and writes. `PINCache` coordinates them so that objects added to memory are available immediately to other threads while being written to disk safely in the background. Both caches are public properties of `PINCache`, so it's easy to manipulate one or the other separately if necessary.
-
-Collections work too. Thanks to the magic of `NSKeyedArchiver`, objects repeated in a collection only occupy the space of one on disk:
-
-```objective-c
-NSArray *images = @[ image, image, image ];
-[[PINCache sharedCache] setObject:images forKey:@"images"];
-NSLog(@"3 for the price of 1: %d", [[[PINCache sharedCache] diskCache] byteCount]);
-```
-
-## Installation
-
-### Manually
-
-[Download the latest tag](https://github.com/pinterest/PINCache/tags) and drag the `PINCache` folder into your Xcode project.
-
-Install the docs by double clicking the `.docset` file under `docs/`, or view them online at [cocoadocs.org](http://cocoadocs.org/docsets/PINCache/)
-
-### Git Submodule
-
-    git submodule add https://github.com/pinterest/PINCache.git
-    git submodule update --init
-
-### CocoaPods
-
-Add [PINCache](http://cocoapods.org/?q=name%3APINCache) to your `Podfile` and run `pod install`.
-
-### Carthage
-
-Add the following line to your `Cartfile` and run `carthage update --platform ios`. Then follow [this instruction of Carthage](https://github.com/carthage/carthage#adding-frameworks-to-unit-tests-or-a-framework) to embed the framework.

-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-   to the Licensor or its representatives, including but not limited to
-   communication on electronic mailing lists, source code control systems,
-   and issue tracking systems that are managed by, or on behalf of, the

-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   copyright license to reproduce, prepare Derivative Works of,
-   publicly display, publicly perform, sublicense, and distribute the
-   Work and such Derivative Works in Source or Object form.
-
-3. Grant of Patent License. Subject to the terms and conditions of
-   this License, each Contributor hereby grants to You a perpetual,
-   worldwide, non-exclusive, no-charge, royalty-free, irrevocable
-   (except as stated in this section) patent license to make, have made,

-   where such license applies only to those patent claims licensable
-   by such Contributor that are necessarily infringed by their
-   Contribution(s) alone or by combination of their Contribution(s)
-   with the Work to which such Contribution(s) was submitted. If You
-   institute patent litigation against any entity (including a
-   cross-claim or counterclaim in a lawsuit) alleging that the Work
-   or a Contribution incorporated within the Work constitutes direct
-   or contributory patent infringement, then any patent licenses
-   granted to You under this License for that Work shall terminate
-   as of the date such litigation is filed.
-

-       the Derivative Works; and
-
-   (d) If the Work includes a "NOTICE" text file as part of its
-       distribution, then any Derivative Works that You distribute must
-       include a readable copy of the attribution notices contained
-       within such NOTICE file, excluding those notices that do not
-       pertain to any part of the Derivative Works, in at least one
-       of the following places: within a NOTICE text file distributed
-       as part of the Derivative Works; within the Source form or
-       documentation, if provided along with the Derivative Works; or,
-       within a display generated by the Derivative Works, if and
-       wherever such third-party notices normally appear. The contents
-       of the NOTICE file are for informational purposes only and
-       do not modify the License. You may add Your own attribution
-       notices within Derivative Works that You distribute, alongside

-   the conditions stated in this License.

-5. Submission of Contributions. Unless You explicitly state otherwise,
-   any Contribution intentionally submitted for inclusion in the Work
-   by You to the Licensor shall be under the terms and conditions of
-   this License, without any additional terms or conditions.
-   Notwithstanding the above, nothing herein shall supersede or modify
-   the terms of any separate license agreement you may have executed
-   with Licensor regarding such Contributions.
-
-6. Trademarks. This License does not grant permission to use the trade
-   names, trademarks, service marks, or product names of the Licensor,
-   except as required for reasonable and customary use in describing the
-   origin of the Work and reproducing the content of the NOTICE file.
-
-7. Disclaimer of Warranty. Unless required by applicable law or
-   agreed to in writing, Licensor provides the Work (and each
-   Contributor provides its Contributions) on an "AS IS" BASIS,
-   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
-   implied, including, without limitation, any warranties or conditions
-   of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
-   PARTICULAR PURPOSE. You are solely responsible for determining the
-   appropriateness of using or redistributing the Work and assume any
-   risks associated with Your exercise of permissions under this License.
-
-8. Limitation of Liability. In no event and under no legal theory,
-   whether in tort (including negligence), contract, or otherwise,
-   unless required by applicable law (such as deliberate and grossly
-   negligent acts) or agreed to in writing, shall any Contributor be
-   liable to You for damages, including any direct, indirect, special,
-   incidental, or consequential damages of any character arising as a
-   result of this License or out of the use or inability to use the
-   Work (including but not limited to damages for loss of goodwill,
-   work stoppage, computer failure or malfunction, or any and all
-   other commercial damages or losses), even if such Contributor
-   has been advised of the possibility of such damages.

-   and charge a fee for, acceptance of support, warranty, indemnity,
-   or other liability obligations and/or rights consistent with this
-   License. However, in accepting such obligations, You may act only
-   on Your own behalf and on Your sole responsibility, not on behalf
-   of any other Contributor, and only if You agree to indemnify,
-   defend, and hold each Contributor harmless for any liability
-   incurred by, or claims asserted against, such Contributor by reason
-   of your accepting any such warranty or additional liability.

-   by such Contributor that are necessarily infringed by their

-
-Description:
-============
-
-WebP codec: library to encode and decode images in WebP format. This package
-contains the library that can be used in other programs to add WebP support,
-as well as the command line tools 'cwebp' and 'dwebp'.
-
-See http://developers.google.com/speed/webp
-
-The latest source tree is available at
-https://chromium.googlesource.com/webm/libwebp
-
-It is released under the same license as the WebM project.
-See http://www.webmproject.org/license/software/ or the
-file "COPYING" file for details. An additional intellectual
-property rights grant can be found in the file PATENTS.
-
-Building:
-=========
-
-Windows build:
---------------
-
-By running:
-
-  nmake /f Makefile.vc CFG=release-static RTLIBCFG=static OBJDIR=output
-
-the directory output\release-static\(x64|x86)\bin will contain the tools
-cwebp.exe and dwebp.exe. The directory output\release-static\(x64|x86)\lib will
-contain the libwebp static library.
-The target architecture (x86/x64) is detected by Makefile.vc from the Visual
-Studio compiler (cl.exe) available in the system path.
-
-Unix build using makefile.unix:
--------------------------------
-
-On platforms with GNU tools installed (gcc and make), running
-
-  make -f makefile.unix
-
-will build the binaries examples/cwebp and examples/dwebp, along
-with the static library src/libwebp.a. No system-wide installation
-is supplied, as this is a simple alternative to the full installation
-system based on the autoconf tools (see below).
-Please refer to makefile.unix for additional details and customizations.
-
-Using autoconf tools:
----------------------
-Prerequisites:
-A compiler (e.g., gcc), make, autoconf, automake, libtool.
-On a Debian-like system the following should install everything you need for a
-minimal build:
-$ sudo apt-get install gcc make autoconf automake libtool
-
-When building from git sources, you will need to run autogen.sh to generate the
-configure script.
-
-./configure
-make
-make install
-
-should be all you need to have the following files
-
-/usr/local/include/webp/decode.h
-/usr/local/include/webp/encode.h
-/usr/local/include/webp/types.h
-/usr/local/lib/libwebp.*
-/usr/local/bin/cwebp
-/usr/local/bin/dwebp
-
-installed.
-
-Note: A decode-only library, libwebpdecoder, is available using the
-'--enable-libwebpdecoder' flag. The encode library is built separately and can
-be installed independently using a minor modification in the corresponding
-Makefile.am configure files (see comments there). See './configure --help' for
-more options.
-
-SWIG bindings:
---------------
-
-To generate language bindings from swig/libwebp.swig at least swig-1.3
-(http://www.swig.org) is required.
-
-Currently the following functions are mapped:
-Decode:
-  WebPGetDecoderVersion
-  WebPGetInfo
-  WebPDecodeRGBA
-  WebPDecodeARGB
-  WebPDecodeBGRA
-  WebPDecodeBGR
-  WebPDecodeRGB
-
-Encode:
-  WebPGetEncoderVersion
-  WebPEncodeRGBA
-  WebPEncodeBGRA
-  WebPEncodeRGB
-  WebPEncodeBGR
-  WebPEncodeLosslessRGBA
-  WebPEncodeLosslessBGRA
-  WebPEncodeLosslessRGB
-  WebPEncodeLosslessBGR
-
-See swig/README for more detailed build instructions.
-
-Java bindings:
-
-To build the swig-generated JNI wrapper code at least JDK-1.5 (or equivalent)
-is necessary for enum support. The output is intended to be a shared object /
-DLL that can be loaded via System.loadLibrary("webp_jni").
-
-Python bindings:
-
-To build the swig-generated Python extension code at least Python 2.6 is
-required. Python < 2.6 may build with some minor changes to libwebp.swig or the
-generated code, but is untested.
-
-Encoding tool:
-==============
-
-The examples/ directory contains tools for encoding (cwebp) and
-decoding (dwebp) images.
-
-The easiest use should look like:
-  cwebp input.png -q 80 -o output.webp
-which will convert the input file to a WebP file using a quality factor of 80
-on a 0->100 scale (0 being the lowest quality, 100 being the best. Default
-value is 75).
-You might want to try the -lossless flag too, which will compress the source
-(in RGBA format) without any loss. The -q quality parameter will in this case
-control the amount of processing time spent trying to make the output file as
-small as possible.
-
-A longer list of options is available using the -longhelp command line flag:
-
-> cwebp -longhelp
-Usage:
- cwebp [-preset <...>] [options] in_file [-o out_file]
-
-If input size (-s) for an image is not specified, it is
-assumed to be a PNG, JPEG, TIFF or WebP file.
-
-Options:

-Experimental Options:
-  -jpeg_like ............. roughly match expected JPEG size
-  -af .................... auto-adjust filter strength
-  -pre <int> ............. pre-processing filter
-
-The main options you might want to try in order to further tune the
-visual quality are:
- -preset
- -sns
- -f
- -m
-
-Namely:
-  * 'preset' will set up a default encoding configuration targeting a
-     particular type of input. It should appear first in the list of options,
-     so that subsequent options can take effect on top of this preset.
-     Default value is 'default'.
-  * 'sns' will progressively turn on (when going from 0 to 100) some additional
-     visual optimizations (like: segmentation map re-enforcement). This option
-     will balance the bit allocation differently. It tries to take bits from the
-     "easy" parts of the picture and use them in the "difficult" ones instead.
-     Usually, raising the sns value (at fixed -q value) leads to larger files,
-     but with better quality.
-     Typical value is around '75'.
-  * 'f' option directly links to the filtering strength used by the codec's
-     in-loop processing. The higher the value, the smoother the
-     highly-compressed area will look. This is particularly useful when aiming
-     at very small files. Typical values are around 20-30. Note that using the
-     option -strong/-nostrong will change the type of filtering. Use "-f 0" to
-     turn filtering off.
-  * 'm' controls the trade-off between encoding speed and quality. Default is 4.
-     You can try -m 5 or -m 6 to explore more (time-consuming) encoding
-     possibilities. A lower value will result in faster encoding at the expense
-     of quality.
-
-Decoding tool:
-==============
-
-There is a decoding sample in examples/dwebp.c which will take
-a .webp file and decode it to a PNG image file (amongst other formats).
-This is simply to demonstrate the use of the API. You can verify the
-file test.webp decodes to exactly the same as test_ref.ppm by using:
-
- cd examples
- ./dwebp test.webp -ppm -o test.ppm
- diff test.ppm test_ref.ppm
-
-The full list of options is available using -h:
-
-> dwebp -h
-Usage: dwebp in_file [options] [-o out_file]
-
-Decodes the WebP image file to PNG format [Default]
-Use following options to convert into alternate image formats:
-  -pam ......... save the raw RGBA samples as a color PAM
-  -ppm ......... save the raw RGB samples as a color PPM
-  -bmp ......... save as uncompressed BMP format
-  -tiff ........ save as uncompressed TIFF format
-  -pgm ......... save the raw YUV samples as a grayscale PGM
-                 file with IMC4 layout
-  -yuv ......... save the raw YUV samples in flat layout
-
- Other options are:
-  -version  .... print version number and exit

-  -incremental . use incremental decoding (useful for tests)
-  -h     ....... this help message
-  -v     ....... verbose (e.g. print encoding/decoding times)
-  -quiet ....... quiet mode, don't print anything
-  -noasm ....... disable all assembly optimizations
-
-Visualization tool:
-===================
-
-There's a little self-serve visualization tool called 'vwebp' under the

-
-Encoding API:
-=============
-
-The main encoding functions are available in the header src/webp/encode.h
-The ready-to-use ones are:
-size_t WebPEncodeRGB(const uint8_t* rgb, int width, int height, int stride,
-                     float quality_factor, uint8_t** output);
-size_t WebPEncodeBGR(const uint8_t* bgr, int width, int height, int stride,
-                     float quality_factor, uint8_t** output);
-size_t WebPEncodeRGBA(const uint8_t* rgba, int width, int height, int stride,
-                      float quality_factor, uint8_t** output);
-size_t WebPEncodeBGRA(const uint8_t* bgra, int width, int height, int stride,
-                      float quality_factor, uint8_t** output);
-
-They will convert raw RGB samples to a WebP data. The only control supplied
-is the quality factor.
-
-There are some variants for using the lossless format:
-
-size_t WebPEncodeLosslessRGB(const uint8_t* rgb, int width, int height,
-                             int stride, uint8_t** output);
-size_t WebPEncodeLosslessBGR(const uint8_t* bgr, int width, int height,
-                             int stride, uint8_t** output);
-size_t WebPEncodeLosslessRGBA(const uint8_t* rgba, int width, int height,
-                              int stride, uint8_t** output);
-size_t WebPEncodeLosslessBGRA(const uint8_t* bgra, int width, int height,
-                              int stride, uint8_t** output);
-
-Of course in this case, no quality factor is needed since the compression
-occurs without loss of the input values, at the expense of larger output sizes.
-
-Advanced encoding API:
-----------------------
-
-A more advanced API is based on the WebPConfig and WebPPicture structures.
-
-WebPConfig contains the encoding settings and is not tied to a particular
-picture.
-WebPPicture contains input data, on which some WebPConfig will be used for
-compression.
-The encoding flow looks like:
-
--------------------------------------- BEGIN PSEUDO EXAMPLE
-
-#include <webp/encode.h>
-
-  // Setup a config, starting form a preset and tuning some additional
-  // parameters
-  WebPConfig config;
-  if (!WebPConfigPreset(&config, WEBP_PRESET_PHOTO, quality_factor))
-    return 0;   // version error
-  }
-  // ... additional tuning
-  config.sns_strength = 90;
-  config.filter_sharpness = 6;
-  config_error = WebPValidateConfig(&config);  // not mandatory, but useful
-
-  // Setup the input data
-  WebPPicture pic;
-  if (!WebPPictureInit(&pic)) {
-    return 0;  // version error
-  }
-  pic.width = width;
-  pic.height = height;
-  // allocated picture of dimension width x height
-  if (!WebPPictureAllocate(&pic)) {
-    return 0;   // memory error
-  }
-  // at this point, 'pic' has been initialized as a container,
-  // and can receive the Y/U/V samples.
-  // Alternatively, one could use ready-made import functions like
-  // WebPPictureImportRGB(), which will take care of memory allocation.
-  // In any case, past this point, one will have to call
-  // WebPPictureFree(&pic) to reclaim memory.
-
-  // Set up a byte-output write method. WebPMemoryWriter, for instance.
-  WebPMemoryWriter wrt;
-  WebPMemoryWriterInit(&wrt);     // initialize 'wrt'
-
-  pic.writer = MyFileWriter;
-  pic.custom_ptr = my_opaque_structure_to_make_MyFileWriter_work;
-
-  // Compress!
-  int ok = WebPEncode(&config, &pic);   // ok = 0 => error occurred!
-  WebPPictureFree(&pic);  // must be called independently of the 'ok' result.
-
-  // output data should have been handled by the writer at that point.
-  // -> compressed data is the memory buffer described by wrt.mem / wrt.size
-
-  // deallocate the memory used by compressed data
-  WebPMemoryWriterClear(&wrt);
-
--------------------------------------- END PSEUDO EXAMPLE
-
-Decoding API:
-=============
-
-This is mainly just one function to call:
-
-#include "webp/decode.h"
-uint8_t* WebPDecodeRGB(const uint8_t* data, size_t data_size,
-                       int* width, int* height);
-
-Please have a look at the file src/webp/decode.h for the details.
-There are variants for decoding in BGR/RGBA/ARGB/BGRA order, along with
-decoding to raw Y'CbCr samples. One can also decode the image directly into a
-pre-allocated buffer.
-
-To detect a WebP file and gather the picture's dimensions, the function:
-  int WebPGetInfo(const uint8_t* data, size_t data_size,
-                  int* width, int* height);
-is supplied. No decoding is involved when using it.
-
-Incremental decoding API:
-=========================
-
-In the case when data is being progressively transmitted, pictures can still
-be incrementally decoded using a slightly more complicated API. Decoder state
-is stored into an instance of the WebPIDecoder object. This object can be
-created with the purpose of decoding either RGB or Y'CbCr samples.
-For instance:
-
-  WebPDecBuffer buffer;
-  WebPInitDecBuffer(&buffer);
-  buffer.colorspace = MODE_BGR;
-  ...
-  WebPIDecoder* idec = WebPINewDecoder(&buffer);
-
-As data is made progressively available, this incremental-decoder object
-can be used to decode the picture further. There are two (mutually exclusive)
-ways to pass freshly arrived data:
-
-either by appending the fresh bytes:
-
-  WebPIAppend(idec, fresh_data, size_of_fresh_data);
-
-or by just mentioning the new size of the transmitted data:
-
-  WebPIUpdate(idec, buffer, size_of_transmitted_buffer);
-
-Note that 'buffer' can be modified between each call to WebPIUpdate, in
-particular when the buffer is resized to accommodate larger data.
-
-These functions will return the decoding status: either VP8_STATUS_SUSPENDED if
-decoding is not finished yet or VP8_STATUS_OK when decoding is done. Any other
-status is an error condition.
-
-The 'idec' object must always be released (even upon an error condition) by
-calling: WebPDelete(idec).
-
-To retrieve partially decoded picture samples, one must use the corresponding
-method: WebPIDecGetRGB or WebPIDecGetYUVA.
-It will return the last displayable pixel row.
-
-Lastly, note that decoding can also be performed into a pre-allocated pixel
-buffer. This buffer must be passed when creating a WebPIDecoder, calling
-WebPINewRGB() or WebPINewYUVA().
-
-Please have a look at the src/webp/decode.h header for further details.
-
-Advanced Decoding API:
-======================
-
-WebP decoding supports an advanced API which provides on-the-fly cropping and
-rescaling, something of great usefulness on memory-constrained environments like
-mobile phones. Basically, the memory usage will scale with the output's size,
-not the input's, when one only needs a quick preview or a zoomed in portion of
-an otherwise too-large picture. Some CPU can be saved too, incidentally.
-

-     WebPDecoderConfig config;
-     CHECK(WebPInitDecoderConfig(&config));

-     config.output.colorspace = MODE_BGRA;
-     // Optionally, the config.output can be pointed to an external buffer as

-     // should be big enough to store the decoded picture.
-     config.output.u.RGBA.rgba = (uint8_t*) memory_buffer;

-       } else {
-         break;
-       }
-     }

-             'file.xmp' contains the XMP metadata to be set
-
-STRIP_OPTIONS:
- Strip color profile/metadata:
-   icc       strip ICC profile
-   exif      strip EXIF metadata
-   xmp       strip XMP metadata
-
-FRAME_OPTIONS(i):
- Create animation:
-   file_i +di+[xi+yi[+mi[bi]]]
-   where:    'file_i' is the i'th animation frame (WebP format),
-             'di' is the pause duration before next frame,
-             'xi','yi' specify the image offset for this frame,
-             'mi' is the dispose method for this frame (0 or 1),
-             'bi' is the blending method for this frame (+b or -b)
-
-LOOP_COUNT:
- Number of times to repeat the animation.
- Valid range is 0 to 65535 [Default: 0 (infinite)].
-
-BACKGROUND_COLOR:
- Background color of the canvas.
-  A,R,G,B
-  where:    'A', 'R', 'G' and 'B' are integers in the range 0 to 255 specifying
-            the Alpha, Red, Green and Blue component values respectively
-            [Default: 255,255,255,255]
-
-INPUT & OUTPUT are in WebP format.
-
-Note: The nature of EXIF, XMP and ICC data is not checked and is assumed to be
-valid.
-
-Visualization tool:
-===================
-
-The examples/ directory also contains a tool (vwebp) for viewing WebP files.
-It decodes the image and visualizes it using OpenGL. See the libwebp README
-for details on building and running this program.
-
-Mux API:
-========
-The Mux API contains methods for adding data to and reading data from WebP
-files. This API currently supports XMP/EXIF metadata, ICC profile and animation.
-Other features may be added in subsequent releases.
-
-Example#1 (pseudo code): Creating a WebPMux object with image data, color
-profile and XMP metadata.
-
-  int copy_data = 0;
-  WebPMux* mux = WebPMuxNew();
-  // ... (Prepare image data).
-  WebPMuxSetImage(mux, &image, copy_data);
-  // ... (Prepare ICC profile data).
-  WebPMuxSetChunk(mux, "ICCP", &icc_profile, copy_data);
-  // ... (Prepare XMP metadata).
-  WebPMuxSetChunk(mux, "XMP ", &xmp, copy_data);
-  // Get data from mux in WebP RIFF format.
-  WebPMuxAssemble(mux, &output_data);
-  WebPMuxDelete(mux);
-  // ... (Consume output_data; e.g. write output_data.bytes to file).
-  WebPDataClear(&output_data);
-
-
-Example#2 (pseudo code): Get image and color profile data from a WebP file.
-
-  int copy_data = 0;
-  // ... (Read data from file).
-  WebPMux* mux = WebPMuxCreate(&data, copy_data);
-  WebPMuxGetFrame(mux, 1, &image);
-  // ... (Consume image; e.g. call WebPDecode() to decode the data).
-  WebPMuxGetChunk(mux, "ICCP", &icc_profile);
-  // ... (Consume icc_profile).
-  WebPMuxDelete(mux);
-  free(data);
-
-
-For a detailed Mux API reference, please refer to the header file
-(src/webp/mux.h).
-
-Demux API:
-==========
-The Demux API enables extraction of images and extended format data from
-WebP files. This API currently supports reading of XMP/EXIF metadata, ICC
-profile and animated images. Other features may be added in subsequent
-releases.
-
-Code example: Demuxing WebP data to extract all the frames, ICC profile
-and EXIF/XMP metadata.
-
-  WebPDemuxer* demux = WebPDemux(&webp_data);
-  uint32_t width = WebPDemuxGetI(demux, WEBP_FF_CANVAS_WIDTH);
-  uint32_t height = WebPDemuxGetI(demux, WEBP_FF_CANVAS_HEIGHT);
-  // ... (Get information about the features present in the WebP file).
-  uint32_t flags = WebPDemuxGetI(demux, WEBP_FF_FORMAT_FLAGS);
-
-  // ... (Iterate over all frames).
-  WebPIterator iter;
-  if (WebPDemuxGetFrame(demux, 1, &iter)) {
-    do {
-      // ... (Consume 'iter'; e.g. Decode 'iter.fragment' with WebPDecode(),
-      // ... and get other frame properties like width, height, offsets etc.
-      // ... see 'struct WebPIterator' below for more info).
-    } while (WebPDemuxNextFrame(&iter));
-    WebPDemuxReleaseIterator(&iter);
-  }
-
-  // ... (Extract metadata).
-  WebPChunkIterator chunk_iter;
-  if (flags & ICCP_FLAG) WebPDemuxGetChunk(demux, "ICCP", 1, &chunk_iter);
-  // ... (Consume the ICC profile in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  if (flags & EXIF_FLAG) WebPDemuxGetChunk(demux, "EXIF", 1, &chunk_iter);
-  // ... (Consume the EXIF metadata in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  if (flags & XMP_FLAG) WebPDemuxGetChunk(demux, "XMP ", 1, &chunk_iter);
-  // ... (Consume the XMP metadata in 'chunk_iter.chunk').
-  WebPDemuxReleaseChunkIterator(&chunk_iter);
-  WebPDemuxDelete(demux);
-
-
-For a detailed Demux API reference, please refer to the header file
-(src/webp/demux.h).
-
-AnimEncoder API:
-================
-The AnimEncoder API can be used to create animated WebP images.
-
-Code example:
-
-  WebPAnimEncoderOptions enc_options;
-  WebPAnimEncoderOptionsInit(&enc_options);
-  // ... (Tune 'enc_options' as needed).
-  WebPAnimEncoder* enc = WebPAnimEncoderNew(width, height, &enc_options);
-  while(<there are more frames>) {
-    WebPConfig config;
-    WebPConfigInit(&config);
-    // ... (Tune 'config' as needed).
-    WebPAnimEncoderAdd(enc, frame, duration, &config);
-  }
-  WebPAnimEncoderAssemble(enc, webp_data);
-  WebPAnimEncoderDelete(enc);
-  // ... (Write the 'webp_data' to a file, or re-mux it further).
-
-
-For a detailed AnimEncoder API reference, please refer to the header file
-(src/webp/mux.h).

-// For multi-threaded decoding we need to use 3 rows of 16 pixels as delay line.
-//
-// Reason is: the deblocking filter cannot deblock the bottom horizontal edges
-// immediately, and needs to wait for first few rows of the next macroblock to
-// be decoded. Hence, deblocking is lagging behind by 4 or 8 pixels (depending
-// on strength).
-// With two threads, the vertical positions of the rows being decoded are:
-// Decode:  [ 0..15][16..31][32..47][48..63][64..79][...
-// Deblock:         [ 0..11][12..27][28..43][44..59][...
-// If we use two threads and two caches of 16 pixels, the sequence would be:
-// Decode:  [ 0..15][16..31][ 0..15!!][16..31][ 0..15][...
-// Deblock:         [ 0..11][12..27!!][-4..11][12..27][...
-// The problem occurs during row [12..15!!] that both the decoding and
-// deblocking threads are writing simultaneously.
-// With 3 cache lines, one get a safe write pattern:
-// Decode:  [ 0..15][16..31][32..47][ 0..15][16..31][32..47][0..
-// Deblock:         [ 0..11][12..27][28..43][-4..11][12..27][28...
-// Note that multi-threaded output _without_ deblocking can make use of two
-// cache lines of 16 pixels only, since there's no lagging behind. The decoding
-// and output process have non-concurrent writing:
-// Decode:  [ 0..15][16..31][ 0..15][16..31][...
-// io->put:         [ 0..15][16..31][ 0..15][...

-// inline YUV<->RGB conversion function
-//
-// The exact naming is Y'CbCr, following the ITU-R BT.601 standard.
-// More information at: http://en.wikipedia.org/wiki/YCbCr
-// Y = 0.2569 * R + 0.5044 * G + 0.0979 * B + 16
-// U = -0.1483 * R - 0.2911 * G + 0.4394 * B + 128
-// V = 0.4394 * R - 0.3679 * G - 0.0715 * B + 128
-// We use 16bit fixed point operations for RGB->YUV conversion (YUV_FIX).
-//
-// For the Y'CbCr to RGB conversion, the BT.601 specification reads:
-//   R = 1.164 * (Y-16) + 1.596 * (V-128)
-//   G = 1.164 * (Y-16) - 0.813 * (V-128) - 0.391 * (U-128)
-//   B = 1.164 * (Y-16)                   + 2.018 * (U-128)
-// where Y is in the [16,235] range, and U/V in the [16,240] range.
-//
-// The fixed-point implementation used here is:
-//  R = (19077 . y             + 26149 . v - 14234) >> 6
-//  G = (19077 . y -  6419 . u - 13320 . v +  8708) >> 6
-//  B = (19077 . y + 33050 . u             - 17685) >> 6
-// where the '.' operator is the mulhi_epu16 variant:
-//   a . b = ((a << 8) * b) >> 16
-// that preserves 8 bits of fractional precision before final descaling.

-// Encodes the given alpha data via specified compression method 'method'.
-// The pre-processing (quantization) is performed if 'quality' is less than 100.
-// For such cases, the encoding is lossy. The valid range is [0, 100] for
-// 'quality' and [0, 1] for 'method':
-//   'method = 0' - No compression;
-//   'method = 1' - Use lossless coder on the alpha plane only
-// 'filter' values [0, 4] correspond to prediction modes none, horizontal,
-// vertical & gradient filters. The prediction mode 4 will try all the
-// prediction modes 0 to 3 and pick the best one.
-// 'effort_level': specifies how much effort must be spent to try and reduce
-//  the compressed output size. In range 0 (quick) to 6 (slow).
-//
-// 'output' corresponds to the buffer containing compressed alpha data.
-//          This buffer is allocated by this method and caller should call
-//          WebPSafeFree(*output) when done.
-// 'output_size' corresponds to size of this compressed alpha buffer.
-//
-// Returns 1 on successfully encoding the alpha and
-//         0 if either:
-//           invalid quality or method, or
-//           memory allocation for the compressed data fails.

- PINAnimatedImage is a class which decodes GIFs to memory mapped files on disk. Like PINRemoteImageManager,
- it will only decode a GIF one time, regardless of the number of the number of PINAnimatedImages created with
- the same NSData.
- 
- PINAnimatedImage's are also decoded chunks at a time, writing each chunk to a separate file. This allows callback
- and playback to start before the GIF is completely decoded. If a frame is requested beyond what has been processed,
- nil will be returned. Because a fileReady is called on each chunk completion, you can pause playback if you hit a nil
- frame until you receive another fileReady call.
- 
- Internally, PINAnimatedImage attempts to keep only the files it needs open – the last file associated with the requested
- frame and the one after (to prime).
- 
- It's important to note that until infoCompletion is called, it is unsafe to access many of the methods on PINAnimatedImage.

-[PINRemoteImageManager](Pod/Classes/PINRemoteImageManager.h) is an image downloading, processing and caching manager. It uses the concept of download and processing tasks to ensure that even if multiple calls to download or process an image are made, it only occurs one time (unless an item is no longer in the cache). PINRemoteImageManager is backed by GCD and safe to access from multiple threads simultaneously. It ensures that images are decoded off the main thread so that animation performance isn't affected. None of its exposed methods allow for synchronous access. However, it is optimized to call completions on the calling thread if an item is in its memory cache.

-PINRemoteImage supports downloading many types of files. It, of course, supports both PNGs and JPGs. It also supports decoding WebP images if Google's library is available. It even supports returning [FLAnimatedImages](https://github.com/Flipboard/FLAnimatedImage) if it's compiled in (though this can be disabled).

-PINRemoteImage also has two methods to improve the experience of downloading images on slow network connections. The first is support for progressive JPGs. This isn't any old support for progressive JPGs though: PINRemoteImage adds an attractive blur to progressive scans before returning them.

+
+### Support for high resolution images
+Currently there are two ways PINRemoteImage is supporting high resolution images:
+1. If the URL contains an `_2x.` or an `_3x.` postfix it will be automatically handled by PINRemoteImage and the resulting image will be returned at the right scale.
+2. If it's not possible to provide an URL with an `_2x.` or `_3x.` postfix, you can also handle it with a completion handler:
+```objc
+NSURL *url = ...;
+__weak UIImageView *weakImageView = self.imageView;
+[self.imageView pin_setImageFromURL:url completion:^(PINRemoteImageManagerResult * _Nonnull result) {
+  CGFloat scale = UIScreen.mainScreen.scale;
+  if (scale > 1.0) {
+    UIImage *image = result.image;
+    weakImageView.image = [UIImage imageWithCGImage:image.CGImage scale:scale orientation:image.imageOrientation];
+    }
+}];
+```
+
+### Set some limits
+```
+// cache is an instance of PINCache as long as you haven't overridden defaultImageCache
+PINCache *cache = (PINCache *)[[PINRemoteImageManager sharedImageManager] cache];
+// Max memory cost is based on number of pixels, we estimate the size of one hundred 600x600 images as our max memory image cache.
+[[cache memoryCache] setCostLimit:600 * [[UIScreen mainScreen] scale] * 600 * [[UIScreen mainScreen] scale] * 100];
+
+// ~50 MB
+[[cache diskCache] setByteLimit:50 * 1024 * 1024];
+// 30 days
+[[cache diskCache] setAgeLimit:60 * 60 * 24 * 30];
