RectangleObject.topRightRadius
Read-only property; a float value that sets the radius of the top-right corner of the Rectangle object. If RectangleObject.lockFlag is true, trying to set this value has no effect.
To set this value, use document.setRectangleObjectProperty().
document.setRectangleObjectProperty(), RectangleObject.bottomLeftRadius, RectangleObject.bottomRightRadius, RectangleObject.lockFlag, RectangleObject.topLeftRadius
