Hi, How common is it that backends return frame types SANE_FRAME_RED/GREEN/BLUE?
At the moment libksane reserves memory for the whole returned image and in case the backend returns the colors separately they are assembled to "normal" RGB format before the image data is returned to the user. Now there is a need to return the data for large images in chunks in stead of the whole thing at once. So the question is: Is it worth the time to work around this by splitting up the selected area and scanning one part at a time or is these frames only used in very few exotic models? Thanks, K?re
