NAME
       palmtopnm - convert a Palm Bitmap to a PNM image


SYNOPSIS
       palmtopnm

       [-verbose]

       [-rendition N]

       [-showhist] [palmfile] palmtopnm

       -transparent

       [-verbose]

       [palmfile]


DESCRIPTION
       This program is part of Netpbm(1).

       palmtopnm reads a Palm Bitmap as input, from Standard Input or palmfile and produces a PPM image as output.

       Alternatively  (when you specify -transparent), palmtopnm writes the value of the transparent color in the Palm
       Bitmap to Standard Output.

       Palmtopnm can convert Palm Bitmaps with the following features.  This does not  mean  that  it  doesn't  handle
       other features.  These are just the ones we found worth mentioning.

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


       -transparent
              If  the  Palm  Bitmap has a transparent color set, palmtopnm writes the value for that color to Standard
              Output in the form #RRGGBB, where RR, GG, and BB are two-digit hexadecimal numbers indicating a value in
              the range 0 through 255.  If no transparent color is set in the Bitmap, palmtopnm writes nothing.  palm-
              topnm does not generate any output image when you specify -transparent.


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


       -showhist
              This option causes palmtopnm to write a histogram of colors in the input file to Standard Error.

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

       palmtopnm bitmap.palm | ppmcolormask 'palmtopnm -transparent bitmap.palm'


HISTORY
       Before Netpbm 10.23 (July 2004), there was a -forceplain option.  But that had been redundant for a long  time,
       since the Netpbm common option -plain does the same thing.


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