int XIntersectRegion(Region sra, Region srb, Region dr_return);
int XUnionRegion(Region sra, Region srb, Region dr_return);
int XUnionRectWithRegion(XRectangle *rectangle, Region src_region, Region dest_region_return);
int XSubtractRegion(Region sra, Region srb, Region dr_return);
int XXorRegion(Region sra, Region srb, Region dr_return);
int XOffsetRegion(Region r, int dx, int dy);
int XShrinkRegion(Region r, int dx, int dy);
The XUnionRegion function computes the union of two regions.
The XUnionRectWithRegion function updates the destination region from a union of the specified rectangle and the specified source region.
The XSubtractRegion function subtracts srb from sra and stores the results in dr_return.
The XXorRegion function calculates the difference between the union and intersection of two regions.
The XOffsetRegion function moves the specified region by a specified amount.
The XShrinkRegion function reduces the specified region by a specified amount. Positive values shrink the size of the region, and negative values expand the region.
