Clears the GdViewer control, in other words, erases the displayed document from the control. This method only cleans up the displayed area of the GdViewer control, it does not close the loaded document. It also clears the rectangle of area selection, if any is defined, using the
ClearRect method internally. You can display the loaded document using the
Redraw method again.
