NAME

       pcxtoppm - convert a PCX file into a PPM image



SYNOPSIS

       pcxtoppm [-stdpalette] [-verbose] [pcxfile]



DESCRIPTION

       This program is part of Netpbm(1).

       pcxtoppm  reads a PCX file as input and produces a PPM image as output.

       pcxtoppm recognizes the following PCX types:



       ·      Colormapped files with 2-16 colors.

              ’Packed pixel’ format (1, 2 or 4 bits/pixel, 1  plane)  or  bit-
              plane format (1 bit/pixel, 1-4 planes).  The program uses a pre-
              defined standard palette if the  image  does  not  provide  one.
              ’Does  not  provide  one’ means the palette in the PCX header is
              completely black.


       ·      Colormapped files with 256 colors.

              8 bits/pixel, 1 plane, colormap at the end of the file.


       ·      24bit truecolor files.

              24bit RGB: 8 bits/pixel, 3 planes.


       ·      32bit truecolor files.

              24bit RGB + 8bit intensity: 8 bits/pixel, 4 planes.





OPTIONS

       -stdpalette
              This option causes  pcxtoppm  to  use  its  predefined  standard
              palette  even  if the PCX image provides its own.  This is mean-
              ingful only for an image in the 16 color paletted PCX format.

              The image may appear to provide its own palette but in  fact  be
              created  by  a program too primitive to understand palettes that
              created a random palette by accident.
