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

58 In addition to the options common to all programs based on libnetpbm
59 (most notably -quiet, see
60 Common Options ⟨index.html#commonoptions⟩ ), palmtopnm recognizes the
61 following command line options:
62
63
64
65 -verbose
66 Display various interesting information about the input file and
67 process.
68
69
70 -transparent
71 If the Palm Bitmap has a transparent color set, palmtopnm writes
72 the value for that color to Standard Output in the form #RRGGBB,
73 where RR, GG, and BB are two-digit hexadecimal numbers indicat‐
74 ing a value in the range 0 through 255. If no transparent color
75 is set in the Bitmap, palmtopnm writes nothing. palmtopnm does
76 not generate any output image when you specify -transparent.
77
78
79 -rendition N
80 Palm Bitmaps may contain several different renditions of the
81 same image, with different depths. By default, palmtopnm oper‐
82 ates on the first rendition (rendition number 1) in the image.
83 This switch allows you to operate on a different rendition. The
84 value must be between 1 and the number of renditions in the
85 image, inclusive.
86
87
88 -showhist
89 This option causes palmtopnm to write a histogram of colors in
90 the input file to Standard Error.

100 You cannot generate a transparency mask if the Palm Bitmap has a trans‐
101 parent color. However, you can still do this with ppmcolormask with a
102 Netpbm pipe similar to:
103
104 palmtopnm bitmap.palm | ppmcolormask `palmtopnm -transparent bit‐
105 map.palm`

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

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