pcxtoppm - convert a PCX file into a portable pixmap
SYNOPSIS
pcxtoppm [-stdpalette] [-verbose] [pcxfile]
DESCRIPTION
Reads a PCX file as input. Produces a portable pixmap as output. Supported PCX types are:
Colormapped files with 2-16 colors.
"Packed pixel" format (1, 2 or 4 bits/pixel, 1 plane) or bitplane format (1 bit/pixel, 1-4 planes). The program checks the colormap
and uses an internal one if the provided colormap is completely black.
Colormapped files with 256 colors
8 bits/pixel, 1 plane, colormap at the end of the file.
24bit truecolor files
24bit RGB: 8 bits/pixel, 3 planes.
32bit truecolor files
24bit RGB + 8bit intensity: 8 bits/pixel, 4 planes.
OPTIONS -stdpalette
Enforce the use of the internal colormap for files with 16 colors or less.

ppmtopcx - convert a portable pixmap into a PCX file
SYNOPSIS
ppmtopcx [-24bit] [-packed] [-xpos=cols] [-ypos=rows] [ppmfile]
DESCRIPTION
Reads a PPM image as input. Produces a PCX file as output. The type of the PCX file depends on the number of colors in the pixmap:
16 colors or less:
1 bit/pixel, 1-4 planes.
256 colors or less:
8 bits/pixel, 1 plane, colormap at the end of the file.
More than 256 colors:
24bit truecolor file (8 bits/pixel, 3 planes).
OPTIONS -24bit Produce a 24bit truecolor file, even if the pixmap has 256 colors or less.
-packed
Use "packed pixel" format for files with 16 colors or less: 1, 2, or 4 bits/pixel, 1 plane.
-xpos=cols
-ypos=rows
These options set the position of the image in some field (e.g. on a screen) in columns to the right of the left edge and rows below
the top edge. The PCX format contains image position information. Don't confuse this with the position of an area of interest
within the image. For example, using pnmpad to add a 10 pixel left border to an image and then converting that image to PCX with
xpos = 0 is not the same as converting the original image to PCX and setting xpos = 10.
The values may be from -32767 to 32768.
The default for each is zero.
