<h2>NAME</h2>
pcxtoppm - convert a PCX file into a PPM image
<h2 id="synopsis">SYNOPSIS</h2>
<b>pcxtoppm</b>
[<b>-stdpalette</b>]
[<b>-verbose</b>]
[<i>pcxfile</i>]
<h2 id="description">DESCRIPTION</h2>
<p>This program is part of <a href="index.html">Netpbm</a>.
<p><b>pcxtoppm</b> reads a PCX file as input and produces a PPM image
as output.
<p><b>pcxtoppm</b> recognizes the following PCX types:
<ul compact>
<li>Colormapped files with 2-16 colors.
<p>"Packed pixel" format (1, 2 or 4 bits/pixel, 1 plane) or
bitplane format (1 bit/pixel, 1-4 planes). The program uses a
predefined standard palette if the image does not provide one.
"Does not provide one" means the palette in the PCX header is
completely black.
<li>Colormapped files with 256 colors.
<p>8 bits/pixel, 1 plane, colormap at the end of the file.
<li>24bit truecolor files.
<p>24bit RGB: 8 bits/pixel, 3 planes.
<li>32bit truecolor files.
<p>24bit RGB + 8bit intensity: 8 bits/pixel, 4 planes.
</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>pcxtoppm</b> recognizes the following
command line options:
<dl compact>
<dt><b>-stdpalette</b>
<dd>This option causes <b>pcxtoppm</b> to use its predefined standard
palette even if the PCX image provides its own. This is meaningful only
for an image in the 16 color paletted PCX format.
<p>The image may appear to provide its own palette but in fact be created
by a program too primitive to understand palettes that created a random
palette by accident.
<dt><b>-verbose</b>
<dd>Report details of the PCX header.
