<H2>DESCRIPTION</H2>
|
|
|
|

|
|
<A NAME="ixAAC"></A>
|
|

|
|

|
|

|
|
<B>ximtoppm </B>
|
|
|
|
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
|
|
<I>alpha-filename</I>
|
|
|
|
file contains all zero (transparent) alpha values. If you don't specify
|
|
<B>--alphaout</B>,
|
|
|
|
<B>ximtoppm</B>
|
|
|
|
does not generate an alpha file, and if the input image has an alpha channel,
|
|
<B>ximtoppm</B>
|
|
|
|
simply discards it.
|
|
<P>
|
|
If you specify
|
|
<B>-</B>
|
|
|
|
as the filename,
|
|
<B>ximtoppm</B>
|
|
|
|
writes the alpha output to Standard Output and discards the image.
|
|
<P>
|
|
Actually, an Xim image can contain an arbitrary fourth channel -- it need
|
|
not be an Alpha channel.
|
|
<B>ximtoppm</B>
|
|
|
|
extracts any fourth channel it finds as described above; it doesn't matter
|
|
if it is an alpha channel or not.
|
|
<P>
|
|
See
|
|
<B><A HREF="/cgi-bin/man/man2html?1+pnmcomp">pnmcomp</A></B>(1)
|
|
|
|
for one way to use the alpha output file.
