palmtopnm - convert a Palm pixmap into a portable anymap
Reads a Palm pixmap as input, from stdin or
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
generated; no anymap will be output.
- -rendition N
Palm pixmaps may contain several different renditions of the same
pixmap, with different depths. By default,
operates on the first rendition (rendition number 1) in the pixmap.
This switch allows you to operate on a different rendition. 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 package 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
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 modified by Bill Janssen to add color, compression, and
