NAME
       palmtopnm - convert a Palm pixmap into a portable anymap

SYNOPSIS
       palmtopnm [-verbose] [-rendition N] [-showhist]
       [-forceplain] [pnmfile]
       palmtopnm -transparent [-verbose] [pnmfile]

DESCRIPTION
       Reads a Palm pixmap as input, from stdin or pnmfile.  Produces either a portable pixmap as
       output, or writes the value of the transparent color in the Palm pixmap to stdout.

OPTIONS
       -verbose
              Display various interesting information about the input file and process.

       -transparent
              If the Palm pixmap has a transparent color set, the RGB value for that  color  will
              be  written  to  stdout  as in the form #RRGGBB, where RR, GG, and BB are two-digit
              hexadecimal numbers indicating a value between 0 and 255.  If no transparent  color
              is  set in the bitmap, nothing will be output.  No additional output will be gener-
              ated; no anymap will be output.

       -rendition N
              Palm pixmaps may contain several different renditions of the same pixmap, with dif-
              ferent  depths.   By  default, palmtopnm operates on the first rendition (rendition
              number 1) in the pixmap.  This switch allows you to operate on a  different  rendi-
              tion.   The value must be between 1 and the number of renditions in the pixmap, in-
              clusive.

       -showhist
              Writes a histogram of colors in the input file to stderr.

       -forceplain
              Force the output anymap to be in ASCII 'plain' netpbm format.

BUGS
       An additional compression format, "packbits," has been added with PalmOS 4.0.  This  pack-
       age should be updated to handle it.

       You  currently  cannot  generate an alpha mask if the Palm pixmap has a transparent color.
       However, you can still do this with ppmcolormask with a Netpbm pipe similar to:

       palmtopnm pixmap.palm | ppmcolormask `palmtopnm -transparent pixmap.palm`

AUTHORS
       This program was originally written as Tbmptopnm.c, by Ian Goldberg.  It was heavily modi-
       fied by Bill Janssen to add color, compression, and transparency function.
