Zgv v3.0 - GIF/JPEG/PPM/BMP/TGA/PCX/PNG/mrf viewer, for VGA PCs running Linux.

Roadmap
-------
The COPYING file contains a copy of the GPL described above.
See doc/README.src in the source distribution, or doc/README.bin in
the binary distribution for installation details.
README.fonts contains the copyright/license details for the bitmap
fonts (which are from X). It's pretty GPL-ish though, don't worry. :-)
The NEWS file describes the changes made since the last version, and
ChangeLog describes differences between all versions, so if you're
upgrading from an old one, be sure to read one of those.
NB: Documentation files other than COPYING, ChangeLog, the man page,
README.fonts and this README are in the `doc' subdirectory.
Description
-----------
`zgv' is a viewer which views GIF{87,89}a, JPEG/JFIF, PNG,
PBM/PGM/PPM, BMP, TGA, PCX, and mrf files on a VGA or SVGA display,
with a full-screen file selector front-end. It can also be used as a
simple command, with `zgv filename', which bypasses the front-end.
There are many options; check the man page, or try `zgv -h' for
details.
`tnpic', which was formerly part of the zgv distribution, is now
available separately.
The mrf format
--------------
`mrf' is a format I devised (which zgv now supports) for storing
certain kinds of 1-bit mono pictures. For suitable images (line-art
and most other high-contrast pictures) it compresses better than GIF
and even PNG - yet it uses a far simpler compression algorithm than
either of those. There are public domain convertors to/from mrf on
sunsite.unc.edu in /pub/Linux/apps/graphics/convert, both in the
pbmtomrf tgz. You can find further information on the format in the
documentation there.
A note for anyone interested in adding support for mrf to image
viewers etc. - you won't believe how easy it is. (And even if you
don't agree, you're perfectly welcome to just base a file reader on
mrftopbm.)
Er, sorry for the gratuitous advert... :-)
