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.
