[comp.sys.amiga.graphics] PBMPlus 24 bit ILBM -> PPM?!?!?

cowgilc@prism.cs.orst.edu (Clayton Cowgill) (06/28/91)

Grumble...

I just got the PBMPlus archive from ab20. I have some ILBM-24 bit files that 
I want to mess with. Now then, I tried using ilbmtoppm on a 24 bit file from
DCTV. ilbmtoppm complains that there are too many bit planes and I should try
to recompile with a larger 'pixval'. Fine. I don't have the sources...

Does anyone have a version of 'ilbmtoppm' that works with ILBM24 files from
DCTV that they'd be willing to send me? A pointer to an anon ftp site that has
one? A pointer to Amiga sources? Anything?

(Someone was also suggesting a program called 'xv' for doing 24->8bit gif
conversions... It's PD, any ideas where I could find it?)

Thanks in advance for any help. I'm still new to the Amiga, but it certainly
is more of a pain in the ass than I was hoping... (I'm originally a Mac/ST/PC/
X11 type person... hence all the confusion... :-)

I have modified ilbmtoppm to accept 24 IFFs. The problem is, you will need
to compile it with the pbmplus libraries. To avoid this, I plan on including
the pertinent library routines into ilbmtoppm.c so that it will compile
and run all on its own. You will have to wait for this though because I leave
for a week long vacation today. When I get back I'll whip it out.

That was probably me. 'xv' accepts 24bit ppm format files but not IFFs.
It does one of the best jobs I have seen for 8bit quantization and supports
GIF, PBM, PPM, PGM, X11 bitmap, and a couple others. It is available on
EXPORT.LCS.MIT.EDU (18.30.0.238) as /contrib/xv.pl3.tar.Z.
