<h2>NAME</h2>
palmtopnm - convert a Palm Bitmap to a PNM image

<h2 id="description">DESCRIPTION</h2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>palmtopnm</b> reads a Palm Bitmap as input, from Standard Input or
<i>palmfile</i> and produces a PPM image as output.
<p>Alternatively (when you specify <b>-transparent</b>),
<b>palmtopnm</b> writes the value of the transparent color in the Palm
Bitmap to Standard Output.
<p><b>Palmtopnm</b> 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.
<ul>
<li>Version 0
<li>Version 1
<li>Version 2
<li>Version 3 (new in Netpbm 10.27 (March 2005))
<li>Scanline compression
<li>RLE compression
<li>Packbits compression (new in Netpbm 10.27 (March 2005))
</ul>
<h2 id="options">OPTIONS</h2>
<p>In addition to the options common to all programs based on libnetpbm
(most notably <b>-quiet</b>, see <a href="index.html#commonoptions">
Common Options</a>), <b>palmtopnm</b> recognizes the following
command line options:
<dl compact>
<dt><b>-verbose</b>
<dd>
Display various interesting information about the input file and process.
<dt><b>-transparent</b>
<dd>
If the Palm Bitmap has a transparent color set,
<b>palmtopnm</b> 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, <b>palmtopnm</b> writes nothing. <b>palmtopnm</b> does not
generate any output image when you specify <b>-transparent</b>.
<dt><b>-rendition N</b>
<dd>
Palm Bitmaps may contain several different renditions of the same
image, with different depths. By default, <b>palmtopnm </b> 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, inclusive.
<dt><b>-showhist</b>
<dd>
This option causes <b>palmtopnm</b> to
write a histogram of colors in the input file to Standard Error.

<h2 id="limitations">LIMITATIONS</h2>
<p>You cannot generate a transparency mask if the Palm Bitmap has a
transparent color. However, you can still do this with
<b>ppmcolormask</b> with a Netpbm pipe similar to:
<p>
<b>palmtopnm bitmap.palm |
ppmcolormask `palmtopnm -transparent bitmap.palm`</b>
<h2 id="history">HISTORY</h2>
<p>Before Netpbm 10.23 (July 2004), there was a <b>-forceplain</b>
option. But that had been redundant for a long time, since the Netpbm
common option <b>-plain</b> does the same thing.
<h2 id="authors">AUTHORS</h2>
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.
