Description
Resets the internal state of the canvas to a default state.
Override the Refresh method to implement resetting the state of a canvas. The operations performed by Refresh depend on the actual canvas implementation. In most implementations though, Refresh destroys the graphical objects, such as pen, brush, or font, that were associated with the canvas.
