SYNOPSISximtoppm [--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 con
taining 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.
