ppmtopcx - convert a portable pixmap into a PCX file
ppmtopcx [-24bit] [-packed] [-xpos=cols] [-ypos=rows] [ppmfile]
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).
-24bit Produce a 24bit truecolor file, even if the pixmap has 256
colors or less.
Use "packed pixel" format for files with 16 colors or less: 1,
2, or 4 bits/pixel, 1 plane.
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.
