I know I'm reviving a somewhat old thread here, but I'm trying to use
this code to implement something similar. It's a digital
pan/tilt/zoom camera control, and since I'm panning around a piece of
an image, it's the same situation with an offset image center.
Anyway, I'm modifying these properties real-time, and it's not
changing anything. Is this something that will only work during
startup, or am I doing something wrong? Is there a function I can
call to force the changes to work real-time? Are they too
computationally intensive for this (I don't imagine it would be, since
you can rotate a standard view in a similar way).
