Guido van Rossum 85f7bd5251 Vrec.py, Vrecb.py: 
- call v.SetParam() after v.BindGLWindow()
	 - turn of dithering in mono/grey mode
	 - use prefposition to place the top left corner at (150, 150)
	   (so that the video remains visible during recording)
	 - default width is 256
Vcopy.py: correct typos; more verbose output.
OldVcopy.py: new name for Jack's old grabbing Vcopy.py.
Vstat.py: print values of all video parameters.

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).
 1993-02-25 14:20:13 +00:00
Guido van Rossum b616ebe4e4 Rewrite applypackfactor() using imageop: faster and more general;

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.

files that should be fixed with Vfix.

resizing by the user in Vreceive.
