--- Comment #14 from William Bader <williambader at hotmail.com> ---
I can remove the -nolzw command line option.
xpdf left the flag in GlobalParams, so I thought that it would be useful to
expose it for testing, but I think that you are correct that a -nolzw or
-noflate flag wouldn't serve any purpose.

Thanks for the deflate patch. I was following the example in
http://www.zlib.net/zlib_how.html but I wasn't sure if the stream needed any
header or wrapper to be usable in a postscript filter.

I noticed that the patch creates new DeflateStream files. I currently added my
new code to the end of FlateStream, but I was considering that also because it
allows poppler to use its own internal flate decoder and to use zlib only for
encoding. I want to get it working first, then I'll clean it up.

I could make a new configure flag to enable flate encoding, and then the
encoding and decoding could be configured independently.

I didn't have a chance to work on it today because we are in the middle of an
installation of the system that I am paid to work on.

Regards, William
