NAMEXEmptyRegion, XEqualRegion, XPointInRegion, XRectInRegion − determine if regions are empty or equal

---

SYNTAXBool XEmptyRegion ( Region r ); Bool XEqualRegion ( Region r1 , Region r2 ); Bool XPointInRegion ( Region r , int x , int y ); int XRectInRegion ( Region r , int x , int y , unsigned int width , unsigned int height );

---

ARGUMENTSr Specifies the region. r1 
.ns r2 Specify the two regions. width 
.ns height Specify the width and height, which define the rectangle. x 
.ns y Specify the x and y coordinates, which define the point or the coordinates of the upper-left corner of the rectangle.

---

DESCRIPTIONThe XEmptyRegion function returns True if the region is empty. The XEqualRegion function returns True if the two regions have the same offset, size, and shape. The XPointInRegion function returns True if the point (x, y) is contained in the region r. The XRectInRegion function returns RectangleIn if the rectangle is entirely in the specified region, RectangleOut if the rectangle is entirely out of the specified region, and RectanglePart if the rectangle is partially in the specified region.
