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 indicating 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 operates 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 PalmOS 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.
