Raster Image Functions: Region Processing Functions Where the Region Preempts the Bitmap

If a bitmap has a region, the following functions act on the region, not on the whole bitmap. To determine whether a bitmap has a region, use the L_BitmapHasRgn function. To remove a bitmap region so that these functions act on the bitmap, use the L_FreeBitmapRgn function.
