Drawing Ovals

An oval is a circular or elliptical shape defined by the bounding rectangle that encloses it. You can use the FrameOval procedure to draw its outline, or the PaintOval or FillOval procedure to draw its interior with a pattern. You can use the EraseOval procedure to erase an oval, and you can use the InvertOval procedure to reverse the colors of all pixels within the oval. (Although this procedure operates on color pixels in color graphics ports, the results of InvertOval are predictable only with 1-bit or direct color pixels.)
