FrameRect

To draw an outline inside a rectangle, use the FrameRect procedure.

PROCEDURE FrameRect (r:\xDDRect);

r

The rectangle to frame.

DESCRIPTION

Using the pattern, pattern mode, and size of the graphics pen for the current graphics port, the FrameRect procedure draws an outline just inside the 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 rectangle is mathematically added to the region's boundary.

SPECIAL CONSIDERATIONS

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