I’m developing a texture atlas packer to use with OpenGL, and I’m currently looking for an open-source (it’s better if it’s a library, but an open-source software would be good as well!) solution that will render the best results for color palette creation / dithering. It really doesn’t need to be fast, but needs to achieve optimal results. It would be best if there is a possibility for 4-bit-per-pixel palette generation.

    pngquant is available as a pure C library.

    ImageMagick uses octtree, which is fast, but not the best quality.

    pngquant uses MedianCut with several additional improvements, and is likely to give higher quality.

    pngquant has speed/quality trade-off setting which can improve quality a bit further, and also has custom dithering algorithm (variation of Floyd-Steinberg) that doesn’t add noise to well-quantized areas of the image.
