But after this call destPR doesn't reflect the contents of tempPR. I think that
the problem stems from the call to pixel_regions_register called from within
copy_region. If the pixel region is initialized using
pixel_region_init_data
(like tempPR is) then the subsequent call to pixel_regions_register sets the
data pointer to an incorrect location. Specifically, pixel_region_init_data
sets tempPR->data to the allocated memory, but then pixel_region_register
sets
tempPR-> data to data + y*rowstride + x * bytes, which for this type of
pixel
region is an error.
"
I figure out that the problem was that I had to re-initialize the pixel region
before using it again. Thanks to Pedro and especially to mitch for helping me
along.
