I am faced with a bunch of images that need to be decompressed. They were
squeezed with CCITT Group 4, using a hardware board that is no longer made.
I've turned up a couple of leads, but so far they have fallen through.
Tiffit, in the libs here, is a demo of some libraries for Group 3 and 4, and
TIFF which looks worth investigating. But the number is only asnwered bya fax,
and I never get a reply.
Simon Wynn was good enough to copy for me an extensive PD TIFF library from a
SUN CD-ROM. But the CCITT stuff depends on a file worthy of the Obfuscated C
contest, and is documented NOT to compile on the Mac. (It generates a vital
header file when it is COMPILED, not when it is run, and also allocates
structures > 32K. I could dynamically allocate the structs, but can't see the
fle because I can't generate it, because the generator file file won't
compile).
I found out where to send away for the CCITT "Blue Book" , and may be reduced
to ordering it and coding the whole thing from scratch.
But time's ticking away on my project. Surely there are Group 4 libs for sale
somewhere? I wonder if there's something available from the DOS side?
Thanks…
