NAME

ximtoppm - convert an Xim file to a PPM image

 

SYNOPSIS

ximtoppm

[--alphaout={alpha-filename,-}] [ximfile]

You can abbreviate any option to its shortest unique prefix.

 

DESCRIPTION

This program is part of Netpbm(1).

ximptoppm reads an Xim file as input and produces a PPM image as output. The Xim toolkit is included in the contrib tree of the X.V11R4 release.

 

OPTIONS

--alphaout=alpha-filename
ximtoppm creates a PGM file containing the alpha channel values in the input image. If the input image doesn't contain an alpha channel, the alpha-filename file contains all zero (transparent) alpha values. If you don't specify --alphaout, ximtoppm does not generate an alpha file, and if the input image has an alpha channel, ximtoppm simply discards it.

If you specify - as the filename, ximtoppm writes the alpha output to Standard Output and discards the image.

Actually, an Xim image can contain an arbitrary fourth channel -- it need not be an Alpha channel. ximtoppm extracts any fourth channel it finds as described above; it doesn't matter if it is an alpha channel or not.

See pamcomp(1)foronewaytouse the alpha output file.
