pcdtojpeg converts PCD (Kodak Photo CD) image files into high quality JPEG images. Conversions are at the maximum available PCD resolution, and are fully color managed - no blown highlights or color casts. A C++ PCD decoder library is also available.

JBIG2 is a compression format for lossless and lossy encoding of scanned monochrome documents at moderately high resolution. It is very efficient in that domain, claiming 100:1 compression. jbig2dec is a decoder-only implementation of the format.
Jpegant is a compact JPEG encoder for embedded applications.
It is intended to be executed on small microcontrollers or microprocessors. High speed and small memory usage is its main concern. It implements a subset of JPEG standard.
Now the code contains JPEG decoder so if you decided to use nonstandard transform or entropy coding in encoder you still will be able to decode bitstream (provided that you keep the decoder in sync of course).
