many thanks - this is quite helpful. I've added your changes to the tree,
and as I also found another problem with the encoder, I've added the fix,
too. I've also prepared an "official" :-) new release, available here:
At least with my test images, I can't find any errors now. Please do test
this release and tell me whether there are still any visual glitches.
P.S. For those who are interested in the technical details: when using the
Windows driver, the first compressed block has a size of 509 bytes instead
of 512. I replicated this behaviour at first, but it works better without.
Additionally, I increased the distance to the end of the compressed block
at which a new header is inserted (70 bytes instead of 20).
