NAME
palmtopnm - convert a Palm Bitmap to a PNM image
SYNOPSIS
palmtopnm
[-verbose]
[-rendition N]
[-showhist]
[palmfile] palmtopnm
-transparent
[-verbose]
[palmfile]
DESCRIPTION
This program is part of Netpbm(1).
palmtopnm reads a Palm Bitmap as input, from Standard Input or palmfile
and produces a PPM image as output.
Alternatively (when you specify -transparent), palmtopnm writes the
value of the transparent color in the Palm Bitmap to Standard Output.
Palmtopnm can convert Palm Bitmaps with the following features. This
does not mean that it doesn't handle other features. These are just the
ones we found worth mentioning.
• Version 0
• Version 1
• Version 2
• Version 3 (new in Netpbm 10.27 (March 2005))
• Scanline compression
• RLE compression
• Packbits compression (new in Netpbm 10.27 (March 2005))
OPTIONS
In addition to the options common to all programs based on libnetpbm
(most notably -quiet, see ]8;;index.html#commonoptions\ Common Options]8;;\ ), palmtopnm recognizes the
following command line options:
-verbose
Display various interesting information about the input file and
process.
-transparent
If the Palm Bitmap has a transparent color set, palmtopnm writes
the value for that color to Standard Output in the form #RRGGBB,
where RR, GG, and BB are two-digit hexadecimal numbers indicating
a value in the range 0 through 255. If no transparent color is
set in the Bitmap, palmtopnm writes nothing. palmtopnm does not
generate any output image when you specify -transparent.
-rendition N
Palm Bitmaps may contain several different renditions of the same
image, with different depths. By default, palmtopnm operates on
the first rendition (rendition number 1) in the image. This
switch allows you to operate on a different rendition. The value
must be between 1 and the number of renditions in the image, in-
clusive.
-showhist
This option causes palmtopnm to write a histogram of colors in
the input file to Standard Error.

LIMITATIONS
You cannot generate a transparency mask if the Palm Bitmap has a trans-
parent color. However, you can still do this with ppmcolormask with a
Netpbm pipe similar to:
palmtopnm bitmap.palm | ppmcolormask `palmtopnm -transparent
bitmap.palm`
HISTORY
Before Netpbm 10.23 (July 2004), there was a -forceplain option. But
that had been redundant for a long time, since the Netpbm common option
-plain does the same thing.
AUTHORS
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.
