XIntersectRegion(3)		XLIB FUNCTIONS		   XIntersectRegion(3)

NAME
       XIntersectRegion, XUnionRegion, XUnionRectWithRegion, XSubtractRegion,
       XXorRegion, XOffsetRegion, XShrinkRegion	- region arithmetic

SYNTAX
       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, Re-
	      gion 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);

ARGUMENTS
       dest_region_return
		 Returns the destination region.

       dr_return Returns the result of the computation.	 ds Dy move or shrink

       dx
       dy	 Specify the x and y coordinates, which	define the amount you
		 want to  the specified	region.

       r	 Specifies the region.

       rectangle Specifies the rectangle.

       sra
       srb	 Specify the two regions with which you	want to	perform	the
		 computation.

       src_region
		 Specifies the source region to	be used.

DESCRIPTION
       The XIntersectRegion function computes the intersection of two regions.

       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 re-
       sults 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.
