Guido van Rossum c97d2eddee Change Vinfo and Vaddcache to usr /ufs/guido/bin/sgi/python. 
Don't force packfactor to 1 in header when writing rgb data.
Small bugfixes in Vcopy.
 1993-02-25 14:50:27 +00:00
Guido van Rossum 5e044b7009 - Separated grabbing (which isn't used much!) from VFile. 
- Renamed old Vcopy.py to OldVcopy.py, some cosmetic changes to it (is
  it still needed?)
- Added new Vcopy.py which does everything that Vtime.py does but also
  format conversions, image scaling, and packfactors.
- VFile: make packfactor always a tuple; introduce set and get methods
  for pf, format, and calculate some derived values.
- Added new module GET.py to std library, use it instead of defining
  DM* in VFile.
- Get rid of C programs (new Python programs can do all that they do
  and they probably don't understand the current file format anyway).

Guido van Rossum b616ebe4e4 Rewrite applypackfactor() using imageop: faster and more general;

Guido van Rossum ff3da0502f Microscopic changes, comments/messages changed. 
Real important: turn off FIELDDROP in Vrec.
 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.

Guido van Rossum cfb6bb2a30 Changed the init() interface of LiveVideoOut to read out the window 
size automatically -- the video is always centered.  Added
resizevideo() and reshapewindow() interfaces.  Documented all methods.
Changed Vsend/Vreceive to use the new interface.  Allow window
resizing by the user in Vreceive.
 1992-09-24 16:03:56 +00:00
