NAME
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 col-
ors 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 in-
formation. 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.
