FillCRgn

Use the FillCRgn procedure to fill a region with a pixel pattern.

PROCEDURE FillCRgn (rgn: RgnHandle; ppat: PixPatHandle); 

rgn

A handle to the region to be filled.

ppat

A handle to the PixPat record for the pixel pattern to be used for the fill.

DESCRIPTION

Using the patCopy pattern mode and the pixel pattern defined in a PixPat record (the handle for which you pass in the ppat parameter), the FillCRgn procedure fills the region whose handle you pass in the rgn parameter. This procedure ignores the pnPat, pnMode, and bkPat fields of the current graphics port and leaves the pen location unchanged.

SPECIAL CONSIDERATIONS

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