palmtopnm(1) General Commands Manual palmtopnm(1)
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
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 indicat-
ing 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.
Palm pixmaps may contain several different renditions of the
same pixmap, with different depths. By default, palmtopnm oper-
ates 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
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 Pal-
mOS 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 ppmcolormask
with a Netpbm pipe similar to:
palmtopnm pixmap.palm | ppmcolormask `palmtopnm -transparent
This program was originally written as Tbmptopnm.c, by Ian Goldberg.
It was heavily modified by Bill Janssen to add color, compression, and
