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 bit-
              map, nothing will be output.  No additional output will be generated; no anymap will be output.

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

       -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 package 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`
