xpmtoppm - convert an X11 pixmap to a PPM image |
|
xpmtoppm [--alphaout={alpha-filename,-}] [-verbose] [xpmfile] |
|
This program is part of Netpbm(1). xpbtoppm reads an X11 pixmap (XPM version 1 or 3) as input and produces a PPM image as output. |
|
--alphaout=alpha-filename |
|
xpmtoppm creates a PBM file containing the transparency mask for the image. If the input image doesn’t contain transparency information, the alpha-filename file contains all white (opaque) alpha values. If you don’t specify --alphaout, xpmtoppm does not generate an alpha file, and if the input image has transparency information, xpmtoppm simply discards it. If you specify - as the filename, xpmtoppm writes the alpha output to Standard Output and discards the image. See pamcomp(1)foronewaytouse the alpha output file. xpmtoppm can’t handle a line longer than 8K characters in the the XPM input. If an input line exceeds this limit, xpmtoppm quits with an error message to that effect. Before Netpbm 10.30 (October 2005), the limit was 2K. |
|
--verbose |
|
xpmtoppm prints information about its processing on Standard Error. |
|
The recogized XPM version 3 features are limited. Comments can only be single lines and there must be for every pixel a default colorname for a color type visual. |
