I’m having difficulty finding the best way to generate a stimulus set. I have a larger picture that I show zoomed in slices of. Because the resolution of the slices is small, the slices are scaled up, which is no issue. However, as control I would also like to display these same slices with their pixels shuffled. The issue I run into is shuffling the slice textures shuffles them before they are scaled, and then the shuffled slices get interpolated. Is there a way of obtaining the scaled texture from psychopy that are actually displayed?
One workaround I have been doing is drawing the scaled unshuffled slice to the back buffer and using win._getRegionOfFrame(buffer=‘back’) and then shuffling that image, but this doesn’t seem ideal. Any help would be appreciated.
