PaintRgn

To paint a region with the graphics pen's pattern and pattern mode, use the PaintRgn procedure.

PROCEDURE PaintRgn (rgn:\xDDRgnHandle);

rgn

A handle to the region to paint.

DESCRIPTION

Using the pen pattern and pattern mode for the current graphics port, the PaintRgn procedure draws the interior of the region whose handle you pass in the rgn parameter. The pen location does not change.

SPECIAL CONSIDERATIONS

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

SEE ALSO

You can use the FillRgn procedure, described next, to draw the interior of a region with a pen pattern different from that for the current graphics port.
