void SwRegionRects::Invert

(

)

invert current rectangle

Change the shape, such that holes with be areas and areas are holes now.

Note: If no rects were removed, then the shape is identical to the original shape. As a result, it will be a NULL-SRectangle after inverting.

void SwRegionRects::operator-=

(

const SwRect &

rRect

)

Delete all overlaps of the Rects in array with the given <rRect>

To do so, all existing rectangles have to be either split or deleted.

Parameters

rRect

rectangle with the area that should be deleted
