FrameOval

To draw an outline inside an oval, use the FrameOval procedure.

PROCEDURE FrameOval (r:\xDDRect);

r

The rectangle that defines the oval's boundary.

DESCRIPTION

Using the pattern, pattern mode, and size of the graphics pen for the current graphics port, the FrameOval procedure draws an outline just inside the oval with the bounding rectangle that you specify in the r parameter. The outline is as wide as the pen width and as tall as the pen height. The pen location does not change.

If a region is open and being formed, the outside outline of the new oval is mathematically added to the region's boundary.

SPECIAL CONSIDERATIONS

The FrameOval procedure may move or purge memory blocks in the application heap. Your application should not call this procedure at interrupt time.
