EraseOvalTo erase an oval, use the
PROCEDURE EraseOval (r:\xDDRect);
- The rectangle that defines the oval's boundary.
DESCRIPTIONUsing the background pattern for the current graphics port and the
patCopypattern mode, the
EraseOvalprocedure draws the interior of an oval just inside the bounding rectangle that you specify in the
rparameter. This effectively erases the oval bounded by the specified rectangle.
This procedure leaves the location of the graphics pen unchanged.
EraseOvalprocedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.
patCopypattern mode is described in "Boolean Transfer Modes With 1-Bit Pixels" beginning on page 3-7.
