I'm pretty sure there's code floating around the pyglet mailing list.
I'd be happy to add it to
http://code.astraw.com/projects/motmot/wiki/pygarrayimage if it seems
reasonable. (pygarrayimage goes from numpy array to pyglet texture).
I checked the pyglet users group, and the only mention I see is from:
http://groups.google.com/group/pyglet-users/browse_thread/thread/
5981f764902c7df/888328e19653be1a?lnk=gst&q=numpy#888328e19653be1a
there, he has the solution:
a = numpy.frombuffer(surf_clip.get_data(), numpy.uint8)
a.shape = (sw, sh, 4)
a = a[:,:,0:3] #drop alpha channel
but when I do it (see code below) the image is clearly munged, so I
think the decoding is not quite right.
any ideas?
thanks,
