Is this possible using B4A? The reason for the question i am trying to process very large images and keep on hitting OOM errors. If could separate the processing from the display then I think I could keep within the memory limits. To give you an idea of the size of the images are bitmaps of CAD drawings at A1 or A0 scale. I can load and display a bitmap but then run out of memory when trying to do a scaling or rotation operation.
