I thought of extracting each channel R, G, B; slicing this region from each of the channels and to merge them back together but there is gotta be a shorter way. python WebAs in standard Python, the slicing range is half-open: the highest index bit is not included. Unlike standard Python however, this index corresponds to the leftmost item. Both indices can be omitted from the slice. If the rightmost index is omitted, it is 0 by default.
