I'm looking for compression routines for scanned B/W images.

The compression/decompression should be fairly fast.

They are to be included in a C program, so C code would be nice.

The images are of two kinds:
  * Handwritten text with maybe a sketch. Could be compressed be a
    "lossy" algorithm, since the image quality isn't too critical.
    Perhaps an intelligent way of vectorizing the pixel data could
    be applied (the compression factor is important).
  * Pictures from an electronic microscope, I beleive no loss in
    image quality could be accepted.

There is a need to crypt the data, so a routine for that , which
could be incorporated would be fine...
