Hi Carsten,

   I don't know of existing jpeg code we could use.

You do have open source C code. C is not Java, but it does mean that you could basically translate the code, instead of having to read the spec and design the entire thing from scratch.

For JPEG:

The IJG code, C, "BSD style with acknowledge clause":
  (The ijg.org site was apparently down today.)

Stanford PVRG, C, Public Domain, "don't blame us":
  http://www.panix.com/~eli/jpeg/

About these:

For JPEG 2000 (which should be used way more!):

JPEG 2000, C, BSD license:
  http://www.openjpeg.org/

JasPer, C, BSD style license:
  http://www.ece.uvic.ca/~mdadams/jasper/

JJ2000 (Java reference implementation of JPEG 2000), strange license (only talks about the copyright), but looks like one can use it):
  http://jj2000.epfl.ch/jj_download/index.html
  http://jpeg2000.epfl.ch/

Endre.
