26 This program is part of Netpbm(1).
27
28 palmtopnm reads a Palm Bitmap as input, from Standard Input or palmfile
29 and produces a PPM image as output.
30
31 Alternatively (when you specify -transparent), palmtopnm writes the
32 value of the transparent color in the Palm Bitmap to Standard Output.
33
34 Palmtopnm can convert Palm Bitmaps with the following features. This
35 does not mean that it doesn't handle other features. These are just
36 the ones we found worth mentioning.

61 -transparent
62 If the Palm Bitmap has a transparent color set, palmtopnm writes
63 the value for that color to Standard Output in the form #RRGGBB,
64 where RR, GG, and BB are two-digit hexadecimal numbers indicat‐
65 ing a value in the range 0 through 255. If no transparent color
66 is set in the Bitmap, palmtopnm writes nothing. palmtopnm does
67 not generate any output image when you specify -transparent.

70 -rendition N
71 Palm Bitmaps may contain several different renditions of the
72 same image, with different depths. By default, palmtopnm oper‐
73 ates on the first rendition (rendition number 1) in the image.
74 This switch allows you to operate on a different rendition. The
75 value must be between 1 and the number of renditions in the
76 image, inclusive.
77
78
79 -showhist
80 This option causes palmtopnm to write a histogram of colors in
81 the input file to Standard Error.

91 You cannot generate an alpha mask if the Palm Bitmap has a transparent
92 color. However, you can still do this with ppmcolormask with a Netpbm
93 pipe similar to:
94
95 palmtopnm bitmap.palm | ppmcolormask `palmtopnm -transparent bit‐
96 map.palm`

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

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