This is for processing high-definition images that are composited and printed, so I really have to work with high image qualities. Also, I am working through the imagedata, which is a string of characters, rather than the content of the image. In that sense, the starting format of the image is not entirely relevant. The size of the image is quite relevant. The data within each image is set to have four times the horizontal and vertical resolution of the screen.
