A lightweight C library for image processing, inspired by FFmpeg.

• Load and save BMP images
• Unified in-memory image representation (Img struct)
• Zero external dependencies
• Simple CLI tool included

make            # release build
make debug      # build with sanitizers
make test       # run tests

Requirements: GCC or Clang, Make, Linux/macOS

./imgmpeg input.bmp output.bmp
./imgmpeg -i input.bmp -f grayscale -o output.bmp

#include "imgmpeg.h"

Img *img = img_load("input.bmp");
img_save(img, "output.bmp");
img_free(img);

• Grayscale and color filters
• 3×3 convolution engine
• Image resizing (nearest-neighbor, bilinear)
• PNG/JPEG support
• Filter graph syntax
