SYNOPSISpalmtopnm [-verbose] [-rendition N] [-showhist]
[-forceplain] [pnmfile]
palmtopnm-transparent [-verbose] [pnmfile]
DESCRIPTION
Reads a Palm pixmap as input, from stdin or pnmfile. Pro
duces either a portable pixmap as output, or writes the
value of the transparent color in the Palm pixmap to std
out.
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 addi
tional output will be generated; no anymap will be
output.
-rendition N
Palm pixmaps may contain several different rendi
tions of the same pixmap, with different depths.
By default, palmtopnm operates on the first rendi
tion (rendition number 1) in the pixmap. This
switch allows you to operate on a different rendi
tion. 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.
SEE ALSOpnmtopalm(1), pnm(5)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.
