PPM Stuff
Convert portable pixmap to X11 Pixmap format (version 3) and vice versa
-----------------------------------------------------------------------
The program ppmtoxpm is a modified version of one sent out by Mark Snitily
(mark@zok.uucp) and upgraded to XPM version 2 by Paul Breslaw
(paul@mecazh.uu.ch).
It converts Jeff Poskanzer's (jef@well.sf.ca.us) portable pixmap format
(PBMPlus) into the new X11 pixmap format: XPM version 3 distributed by Arnaud
Le Hors (lehors@mirsa.inria.fr).
It is built using the PBMPlus libraries in the same way as any of the
ppm utilities in the PBMPlus package.

Patches
-------
* Rainer Sinkwitz sinkwitz@ifi.unizh.ch - 21 Nov 91:
xpmtoppm.c:
- Bug fix, no advance of read ptr, would not read
colors like "ac c black" because it would find
the "c" of "ac" and then had problems with "c"
as color.
- Now understands multword X11 color names
- Now reads multiple color keys. Takes the color
of the highest available key. Lines no longer need
to begin with key 'c'.
- expanded line buffer to from 500 to 2048 for bigger files
ppmtoxpm.c:
- Bug fix, should should malloc space for rgbn[j].name+1 in line 441
caused segmentation faults
- lowercase conversion of RGB names def'ed out,
considered harmful.
Suggestions:
ppmtoxpm should read /usr/lib/X11/rgb.txt by default.
With the Imakefiles of pbmplus it even gets compiled
with -DRGB_DB=\"/usr/lib/X11/rgb.txt\"
