XEmptyRegion __libmansuffix__ __xorgversion__ "XLIB FUNCTIONS"
NAME
XEmptyRegion, XEqualRegion, XPointInRegion, XRectInRegion - determine if regions are empty or equal
SYNTAX
Bool 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\^);
ARGUMENTS
r 1i
Specifies the region.
r1 1i
.ns
r2 1i
Specify the two regions.
width 1i
.ns
height 1i
Specify the width and height, which define the rectangle.
x 1i
.ns
y 1i
Specify the x and y coordinates, which define the point
or the coordinates of the upper-left corner of the rectangle.
DESCRIPTION
The
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.
