A Haskell library for loading and storing images, based on the simple stb single-file C libraries.
The same caveats given in stb_image.h obviously still apply to this wrapper, namely:
- no 16-bit-per-channel PNG
- no 12-bit-per-channel JPEG
- no JPEGs with arithmetic coding
- no 1-bit BMP
Formats that can be read:
- JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib)
- PNG 1/2/4/8-bit-per-channel (16 bpc not supported)
- TGA (not sure what subset, if a subset)
- BMP non-1bpp, non-RLE
- PSD (composited view only, no extra channels, 8/16 bit-per-channel)
- GIF
- HDR (radiance rgbE format)
- PIC (Softimage PIC)
- PNM (PPM and PGM binary only)
Formats that can be written:
- PNG (suboptimal, 20-50% larger than a 'reasonably optimised' implementation)
- BMP
- TGA
