NAME¶TickitRectSet - store a collection of rectangular areas
#include <tickit.h> typedef struct TickitRectSet;
DESCRIPTION¶A TickitRectSet instance stores a collection of rectangular areas as non-overlapping regions. Mutation operations allow areas to be added or subtracted. Query operations allow testing for area containment, intersection, or iterating the stored regions.
FUNCTIONS¶A new TickitRectSet instance is created using the tickit_rectset_new(3) function, and destroyed using tickit_rectset_destroy(3).
Rectangular areas can be added using tickit_rectset_add(3) and subtracted using tickit_rectset_subtract(3). The TickitRectSet can be emptied of regions entirely by using tickit_rectset_clear(3). The entire set of regions can be uniformly moved using tickit_rectset_translate(3).
The stored regions can be queried by using tickit_rectset_rects(3) and tickit_rectset_get_rects(3). An area can be tested to see if it is entirely contained in the set using tickit_rectset_contains(3), or that it intersects at all using tickit_rectset_intersects(3).
