New tool Vfix: truncate the right edge of 'grey' type images to make
...
the scanline width a multiple of 4.
VFile: use gl.gversion() to distinguish 4.0.1 and 4.0.5 Indigos;
truncate width and height to multiples of packfactor.
Vinfo: add -t to descriptive comment; print '!' after packfactor for
files that should be fixed with Vfix.

VFile: added new formats 'jpeg' and 'jpeggrey'. Decompression is done
...
using module 'jpeg' by the Displayer class. (Unfortunately it's too
slow for real time.) Print file size in printinfo() method.
Vinfo: added -t option (terse -- one line per file) and usage message.
Vtime: use BasicV{in,out}File classes -- the minimum needed.
Vmkjpeg, Vunjpeg: new utilities for jpeg (de)compression.

Created Vedit.py, the video editor. This uses the classes in Viewer.py.
...
Viewer.py in turn requires changes to VFile.py (unfortunately that file
is now a complete mess...).

1992-08-21 12:41:23 +00:00
