palmtopnm(1) General Commands Manual palmtopnm(1) NAME palmtopnm - convert a Palm pixmap into a portable anymap SYNOPSIS palmtopnm [-verbose] [-rendition N] [-showhist] [-forceplain] [pnmfile] palmtopnm -transparent [-verbose] [pnmfile] DESCRIPTION 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. OPTIONS -verbose Display various interesting information about the input file and process. -transparent 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. -rendition N 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, in- clusive. -showhist Writes a histogram of colors in the input file to stderr. -forceplain Force the output anymap to be in ASCII 'plain' netpbm format. SEE ALSO pnmtopalm(1), pnm(5) BUGS 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` AUTHORS 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. Copyright 1995-2001 by Ian Goldberg and Bill Janssen. 15 December 2000 palmtopnm(1)
