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> <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. </DL> <H2 id="seealso">SEE ALSO</H2> <B><A HREF="pnmtopalm.html">pnmtopalm</A></B>, <A HREF="pnm.html">pnm</A>, <H2 id="limitations">LIMITATIONS</H2> <P>You cannot generate an alpha 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. <p>Copyright 1995-2001 by Ian Goldberg and Bill Janssen. <HR> <H2 id="index">Table Of Contents</H2> <UL> <LI><A HREF="#synopsis">SYNOPSIS</A> <LI><A HREF="#description">DESCRIPTION</A> <LI><A HREF="#options">OPTIONS</A> <LI><A HREF="#seealso">SEE ALSO</A> <LI><A HREF="#limitations">LIMITATIONS</A> <LI><A HREF="#history">HISTORY</A> <LI><A HREF="#authors">AUTHORS</A> </UL> </BODY> </HTML>
