Image rotation is performing a geometric rotation with certain angle on a particular image.

Image rotation is performing a geometric rotation with certain angle on a particular image. An image can be rotated by a positive angle or negative angle, which will rotate the image clockwise or counterclockwise. Rotating an image by 360 degrees or -360 degrees will actually result in the same image as the original image, while rotating on 180 or -180 degrees will display an inverted copy of the original image.
