... Here are the bullet points: decodes baseline JPEG only, no progressive or lossless JPEG supports 8-bit grayscale and YCbCr images, no 16 bit, CMYK or other color spaces supports any power-of-two chroma subsampling ratio supports restart markers the four points above mean that it should be able to decode all digital camera JPEG files and many other JPEG files below 900 lines of code (and that already includes over 200 lines of comments and empty lines!) converts YCbCr to RGB uses a bicubic chrominance upsampling filter (this is actually better than the mere bilinear filter of libjpeg!) a little slower than libjpeg memory requirements: ~512 KiB (static) + 1x the decoded image size for grayscale images or 2x the decoded image size for color images very simple API input: memory dumps of JPEG files output: memory dumps of raw, uncompressed 8-bit grayscale or 24-bit RGB pixels output format is compatible to the PGM/PPM file formats as well as OpenGL GL_LUMINANCE8/GL_RGB8 texture formats not fault-tolerant – any bitstream error will stop the decoder immediately and return an error to the application 100% pure C code no warnings with GCC 4.3 -pedantic and MSVC /W3 32-bit integer arithmetic only supposed to be endianness independent 64-bit clean not thread-safe platform-independent includes some provisions to build ultra-small Win32 executables open source (free-beer, but maybe not really free-speech software) single C file batteries example program included
