[Octave-bug-tracker] [bug #48195] missing getframe function

[Guillaume]

Follow-up Comment #12, bug #48195 (project octave):

I've had other issues with openGL in the past on my machine (with the nvidia
drivers) so it might not be too surprising if it doesn't work straight away (I
tried the demos as well). I don't really know how to investigate further - I
also notice that Octave becomes unstable afterwards and segfault.

Also, I was not suggesting to modify the behavior of getframe - it would still
work with figures or axes handles like in Matlab. My suggestion was to have an
extra function, capturescreen, that getframe would rely on, and with which you
could grab any part of the screen. Not essential but just thought it might be
a great addition. An alternative would be to allow to pass the graphics root
handle (0) to getframe to enable this scenario.
