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).
