NAME

xpmtoppm - convert an X11 pixmap into a PPM image

SYNOPSIS

xpmtoppm [__--alphaout=__{''alpha-filename'',__-__}? [__-verbose__? [''xpmfile''?

DESCRIPTION

Reads an X11 pixmap (XPM version 1 or 3) as input. Produces a PPM file as output.

OPTIONS

--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 pnmcomp(1) for one way to use the alpha output file.

--verbose

xpmtoppm prints information about its processing on Standard Error.

LIMITATIONS

The support to XPM version 3 is limited. Comments can only be single lines and there must be for every pixel a default colorname for a color type visual.
