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.
