Remarks

You can use this class to draw a rectangle on the BitmapViewer control surface. Depending on this control properties you can resize (see ResizeMode property) or move (see Movable property) this rectangle by the mouse. This way this rubberband is extremely useful to make a rectangular selection on the bitmap.

To get or set the rectangle (selection) programmatically, you can use property Rectangle. It will return the rectangle displayed at the BitmapViewer control in coordinates of the bitmap associated with it.

The rectangle can be resized either arbitrary, or only increase or decrease the width and height equally (i.e. preserving the rectangle proportion). It is specified by the ResizeMode property. The required aspect ratio is specified with the Ratio property.

You can specify whether to display a mask which shadows the image out of the rectangle. It is convenient when you use this rubberband together with the Crop transform. Use MaskVisible property for it.
