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,  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);

ARGUMENTS
     dest_region_return
	       Returns the destination region.

     dr_return Returns the result of the computation.

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

     r	       Specifies the region.

     rectangle Specifies the rectangle.

     sra
     srb       Specify the two regions with which you want to perform the compu-
	       tation.

     src_regionSpecifies 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  results
     in dr_return.

     The XXorRegion function calculates the difference between the union and in-
     tersection 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.
