       palmtopnm - convert a Palm Bitmap to a PNM image




       [-rendition N]

       [-showhist] [palmfile] palmtopnm





       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.

              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  indicat-
              ing a value in the range 0 through 255.  If no transparent color
              is set in the Bitmap, palmtopnm writes nothing.  palmtopnm  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  oper-
              ates  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 renditions in the
              image, inclusive.

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

       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


       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.


       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.
