palmtopnm - convert a Palm pixmap into a portable anymap
palmtopnm [-verbose] [-rendition N] [-showhist]
palmtopnm -transparent [-verbose] [pnmfile]
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.
Display various interesting information about the input file and process.
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 bitmap, nothing will be output. No additional output will be gener-
ated; no anymap will be output.
Palm pixmaps may contain several different renditions of the same pixmap, with dif-
ferent depths. By default, palmtopnm operates on the first rendition (rendition
number 1) in the pixmap. This switch allows you to operate on a different rendi-
tion. The value must be between 1 and the number of renditions in the pixmap,
Writes a histogram of colors in the input file to stderr.
Force the output anymap to be in ASCII 'plain' netpbm format.
An additional compression format, "packbits," has been added with PalmOS 4.0. This pack-
age 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`
This program was originally written as Tbmptopnm.c, by Ian Goldberg. It was heavily modi-
fied by Bill Janssen to add color, compression, and transparency function.
