  • jpeg-9b/libjpeg.txt
    A word about functions *not* provided by the library.  We handle a subset of
    the ISO JPEG standard; most baseline, extended-sequential, and progressive
    JPEG processes are supported.  (Our subset includes all features now in common
    use.)  Unsupported ISO options include:
            * Hierarchical storage
            * Lossless JPEG
            * DNL marker
            * Nonintegral subsampling ratios
    We support 8-bit to 12-bit data precision, but this is a compile-time choice
    rather than a run-time choice; hence it is difficult to use different
    precisions in a single application.
