The bitmap is a standard large size image as per taken from the camera. I can generate the screen size image using similar code to the gallery. The problem is that I want to save the final image at normal size (2056x1536, hell I would even settle for 1024x768). To do that I need to create a second bitmap that I can use as the canvas - this is where it always dies. I have code that does pixel by pixel translation but its considerably slower than using colormatrixes. and a canvas.
