Small, vibe-coded script I use to light/darkmode and change orientation on VRChat prints.
I decided to upload it in case it helps anyone else doing the same things.

• Rotate the inner photo (clockwise/counter-clockwise) and rebuild the print box
• Switch between light/dark frame
• Works with the original landscape or the portrait this tool makes
• Non-destructive filenames with suffixes (-orientation, -darkmode / -lightmode)
• Bicubic scaling everywhere it resizes (it never resizes the photo itself; only the box parts)

• VRCprintutils/vrcprintutils.py — interactive CLI tool (Windows/Linux/macOS)
• VRCprintutils/SelectPrintBox-horizontal.atn — Photoshop Action: selects the photo area for landscape prints
• VRCprintutils/SelectPrintBox-vertical.atn — Photoshop Action: selects the photo area for portrait prints

The Photoshop Actions are just helpers I use to isolate the picture, so you can easily color grade it without touching the white/black frame.

You’ll need Python 3.9+ and a terminal.
