The answer is a bit complicated to include in the list.

Lagrange uses stb_image on all platforms. The library supports these formats:

• JPEG baseline & progressive (12 bpc/arithmetic not supported, same as stock IJG lib)
• PNG 1/2/4/8/16-bit-per-channel
• 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 (*comp always reports as 4-channel)
• HDR (radiance rgbE format)
• PIC (Softimage PIC)
• PNM (PPM and PGM binary only)

(GIF animation is NOT supported.)

WebP support is optional but I've included it in most (all?) prebuilt binaries. If you build from source, it may be missing.

I have not verified if all these formats actually work. stb_image can auto-detect many formats, but some may require hints that I'm not providing at the moment.
