<H2>OPTIONS</H2>
<DL COMPACT>
<DT id="1"><B>--alphaout=</B><I>alpha-filename</I>
<DD>
<B>tgatoppm </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>tgatoppm</B>
does not generate an alpha file, and if the input image has an alpha channel,
<B>tgatoppm</B>
simply discards it.
<P>
If you specify
<B>-</B>
as the filename,
<B>tgatoppm</B>
writes the alpha output to Standard Output and discards the image.
<P>
See
<B><A HREF="/cgi-bin/man/man2html?1+pnmcomp">pnmcomp</A></B>(1)
for one way to use the alpha output file.
<DT id="2"><B>--headerdump</B>
<DD>
Causes the header information to be dumped to stderr.
</DL>
<P>
All options can be abbreviated to their shortest unique prefix.
