Minimalist JPEG decoder & encoder

JPEG

Decoder    - written in C99    - can parse YCbCr, YCCK and grayscale images    - can handle 8-bit or 12-bit samples    - can handle subsampled components    - can handle restart markers    - supports interleaved and non-interleaved scans    - supports Motion JPEG    - does not support progressive JPEG files    - does not support arithmetic coding      Encoder         - written in C99         - supports subsampled components (4:4:4, 4:2:2, 4:2:0)         - uses interleaved scan         - supports quality setting (1..100)         - support color and grayscale images         - uses default Huffman table or optimized tables         - can handle 8-bit and 12-bit input images
