NAME
palmtopnm - convert a Palm pixmap into a portable anymap
SYNOPSIS
palmtopnm [-verbose] [-rendition N] [-showhist]
[-forceplain] [pnmfile]
palmtopnm -transparent [-verbose] [pnmfile]
DESCRIPTION
Reads a Palm pixmap as input, from stdin or pnmfile. Produces either a
portable pixmap as output, or writes the value of the transparent color
in the Palm pixmap to stdout.
OPTIONS
-verbose
Display various interesting information about the input file and
process.
-transparent
If the Palm pixmap has a transparent color set, the RGB value
for that color will be written to stdout as in the form #RRGGBB,
where RR, GG, and BB are two-digit hexadecimal numbers indicat-
ing a value between 0 and 255. If no transparent color is set
in the bitmap, nothing will be output. No additional output
will be generated; no anymap will be output.
-rendition N
Palm pixmaps may contain several different renditions of the
same pixmap, with different depths. By default, palmtopnm oper-
ates on the first rendition (rendition number 1) in the pixmap.
This switch allows you to operate on a different rendition. The
value must be between 1 and the number of renditions in the
pixmap, inclusive.
-showhist
Writes a histogram of colors in the input file to stderr.
-forceplain
Force the output anymap to be in ASCII 'plain' netpbm format.

BUGS
An additional compression format, "packbits," has been added with Pal-
mOS 4.0. This package should be updated to handle it.
You currently cannot generate an alpha mask if the Palm pixmap has a
transparent color. However, you can still do this with ppmcolormask
with a Netpbm pipe similar to:
palmtopnm pixmap.palm | ppmcolormask `palmtopnm -transparent
pixmap.palm`

This program was originally written as Tbmptopnm.c, by Ian Goldberg.
It was heavily modified by Bill Janssen to add color, compression, and
transparency function.
