Syntax

The shape discrete feature is specified as one of two acceptable strings, either rect representing a rectangular screen or round representing a circular, oval or elliptical screen.

rect
The shape is an axis aligned rectangle or square, or a similar shape such as rounded rectangle for which the traditional designs are appropriate.
round
The shape is rounded or a similar shape to the circle such as an oval, an ellipse for which distinctively rounded designs are appropriate.
