Mirroring is done by copying. Suppose a Picture has H rows of Pixels and W columns of Pixels and W is an even number, like W is 2N. Here N is a the whole number that is exactly 1/2 of W. How many Pixels are copied when the Picture is mirrored along the vertical line through its middle? <-- I understand what the question is asking. Its just how would I go about doing it? Should I type up a program?
