I have written some rough patches to allow xv-3.00 to read photocd files, and
posted them to alt.sources.

It is pretty crude and was written quickly for a specific purpose and has
not really been cleaned up. It is poorly structured, full of debugging
codes and verbose comments, and there is very little attempt at optimizing
things. No profiling has been done.

There is not yet support for overview files, nor is there a facility to
use the higher resolution chroma planes when viewing lower resolution
images.

All five resolutions can be read however, though one needs an awful lot of
memory to view the largest 3072*2048 resolution.

Its only claim to fame is that it works and produces reasonable looking
images.

The outline of this is shamelessly derived from xvpbm.c to read the
file, and xvtiffwr.c to handle the popup window and X stuff (X never
has been my forte !), and the PhotoCD format information (though not
the code) was found in Hadmut Danisch's (danisch@ira.uka.de) hpcdtoppm
program in which he has reverse engineered the format by studying
hex dumps of PhotoCDs ! After all who can afford the Kodak developer's
kit, which none of us have seen yet ? Am I even allowed to mention these
words (Kodak, PhotoCD) ? I presume they are registered trade marks.

Feel free to send me comments or improvements ... hopefully someone who really
knows what they are doing will tidy it up or do a neater job.
