NAME
ximtoppm - convert an Xim file into a portable pixmap
SYNOPSIS
ximtoppm [--alphaout={alpha-filename,-}] [ximfile]
DESCRIPTION
Reads an Xim file as input. Produces a portable pixmap as output. The Xim toolkit is included in the contrib tree of the X.V11R4 release.
OPTIONS
--alphaout=alpha-filename
ximtoppm creates a PGM (portable graymap) 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 pnmcomp(1) for one way to use the alpha output file.
All options can be abbreviated to their shortest unique prefix.
