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
              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.
