 1992-12-09 22:16:35 +00:00
Guido van Rossum 4df20fa80f 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.
 1992-09-29 17:07:10 +00:00
Guido van Rossum 9e3f335bea 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.
