This file (NEWS) documents the major changes to zgv since the last
version (2.8).
New features added:
- Added `mrf' support. Mrf is a 1-bit-mono-only file format I thought
up while thinking about how you could compress such images more
effectively. For some kinds of input (esp. line-art), it compresses
better than GIF or PNG. (I've also written PD convertors to/from PBM -
look for `pbmtomrf'.)
- Added bitmap fonts (from X, though you don't need X installed). You
can still get the old line-based font if you want, though.
- It now remembers where you were in a directory if you return to it.
So if you go into a subdir then return to the parent dir, the cursor
will be on that subdir.
- Added thumbnails for subdirs. These are made up of the first four
files in the dir squeezed together into a single thumbnail. Details in
the man page.
- Added support for 1152x864 and 1600x1200 modes. You get at them by
prefixing the function key (F1-F8) with tab. (I can't actually test
these modes, but they should work.)
- Zoom mode (for images smaller than the screen) works more sensibly
now, and is roughly twice as fast. (It also happens to fix an
occasional segfault in 320x200 modes - albeit only by completely
replacing the code. An unusual debugging technique, to be sure. :-))
- There's now support for the 640x480 16-colour mode in the viewer.
It works by emulating an 8-bit mode, and either displays in greyscale
(default) or in dithered colour.
- New `smallfiletext' option which reduces the size of the filename
text in the file selector. You may find this useful if you think the
text is too big or if you'd like to see more of the filename.
- Alternatively, you can do `:' in the file selector to display the
full filename of the currently-selected file (or at least, as much as
will fit on a single line).
Bugfixes:
- Previously, if errors occurred when zgv was loading a new file while
the old file was still being displayed, the error message appeared
over the top of the old image (which looked terrible). It now changes
modes to display the message if necessary.
- The 7-missing-or-junk-pixels problem in 320x200 and 320x240 modes
has been fixed (finally).
- Fixed starting-on-unreadable-dir problem.
- Previously, if you started with `visual off', the mid-grey colour
was set to the tagged-file colour (i.e. red). Fixed that.
- Bugs in usage output (i.e. output from zgv -h) fixed.
- Fixed a couple of minor problems with the help pages.
- Fixed a few spelling errors in the man page.
Other changes:
- Updated png support (better late than never :-)). Apparently it was
terribly out of date before and did bad things for some files; thanks
to Greg Roelofs for pointing this out. Hopefully it's reasonably
up-to-date now, and should work with any future versions of libpng.
- Sped directory reading up a little for directories where no files
have any associated thumbnails (i.e. dirs with no `.xvpics' subdir
etc.).
- The help screens now use 256-colour mode (which is faster) in the
same circumstances as the file selector does (i.e. if the mode's
available and not specifically disabled with the force16fs option).
