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

[Philip Nienhuis]

Follow-up Comment #8, bug #48195 (project octave):

I tried the original patch from Panxto and that works like a charm on
Mageia-5. Thanks very much so far!
I've yet to try in Windows (made the build but had no time to install it yet)
but I suppose it'll run fine there as well.

Several years back I looked into it but as my C++ proficiency is lacking and
Octave's graphics system is a bit opaque to me I never got any further than
reading up on OpenGL's glReadpixels :-)

Regarding Panxto's comments: as I understand Matlab's docs, getframe() is
meant to grab (part of) a graphics window, not an arbitrary part of the
users's screen.  Now that wouldn't be an argument to limit it to a graphics
window. Maybe some special Octave-only input arg could help to switch between
graphics window (axis measures) and screen (pixels). 
The next challenge would be capturing remote screens; or maybe a specific
screen in a dual/triple/multiple screens setup.

Let's first make getframe work reliably on a graphics window, then go for more
options ?
