NAME

       tickit_rectset_subtract - subtract a region from a rectangle set

SYNOPSIS

       #include <tickit.h>

       void tickit_rectset_subtract(TickitRectSet *trs, const TickitRect *rect);

       Link with -ltickit.

DESCRIPTION

       tickit_rectset_subtract()  ensures  that  the regions stored by the rectangle set do not include the area
       given by rect. To do this, it may have to split  one  or  more  of  the  existing  regions  into  smaller
       fragments, and so may result in more regions being stored.

RETURN VALUE

       tickit_rectset_subtract() returns no value.
