•The size and shape of the source rectangle are independent of the destination rectangle’s size and shape.

Suppose that you have defined an input’s source and destination rectangles so that a 320 x 240 portion of a video source image is mapped into a 640 x 480 rectangle. Here, the destination rectangle is larger than the source rectangle, but it has the same shape and the same width-to-height aspect ratio (4:3). Thus, the original input image is enlarged (scaled) equally, in both dimensions.

Varying the destination rectangle’s size but preserving its aspect ratio makes the displayed image larger or smaller. As long as its proportions correspond to those of the source rectangle, the output image resembles the input image.

If you independently vary the shape of either the source or destination rectangle, so that their aspect ratios are no longer the same, the displayed picture will appear stretched or squeezed as compared to the original image.

An image can be sized and positioned anywhere on the output display. If the destination rectangle is defined so that a portion is off the screen, that portion of is “clipped” — until it is moved back into view.

Two examples of “image clipping” are illustrated below. In the first example, the full size source rectangle (640 x 480) is mapped to a destination rectangle, starting at (900,100). The right-hand portion of the source image is clipped.
