Hello everyone!Now I had copy/crop the image accroding the ROI. How to fast clear the Old Image(size:320x240) and Create new Image accroding the ROI point width and heigh(40x50).Thanks !
Not quite sure what you are trying to do? Have you looked at copy(), clear(), Image()?
Thanks kwagyeman for kindly support.I want to only show img17 in IDE from this code.But it glitter always.Thanks!
