Specifies the width and height of the view for a stacked canvas. The size and position of the view define the part of the canvas that is actually displayed in the window at runtime.
Note: For a content or toolbar canvas, the view is represented by the window to which the canvas is assigned, and so the Viewport Height and Viewport Width properties do not apply.
