Hi All.
My purpose is very simple:I want to capture my desktop to generate an
image, then do some stuff to it.
Or it may be not so easy to accomplish this. Can anyone give me a guide?
How often do you want to to take a snapshot of the screen (often
called screen scraping)?
The fastest way to do this currently is to attach a full screen
context to the display(s) that you want to capture then use OpenGL
commands to read from the frame buffer using that context. However you
may not need this level of read back performance and hence could use a
simpler solution (for example the one Michael W. suggested).
Note "capture" can easily be confused with capturing the screen for
exclusive use (aka game going full screen) so just make sure to keep
the context clear (like you did).
