Thanks J.P. You say that I can call myim->dirty() or myim->setImage(), but wouldn't calling myim->setImage() cause a slow update? That's what I seem to be experiencing. I need to update based on the sensor around 30Hz.
The imagery data (from sensor) is in system memory ... just trying to get a view that shows it without dropping so many frames. Thanks again, Ben On Fri, Feb 26, 2010 at 12:23 AM, J.P.
