NAME

XCreateRegion, XSetRegion, XDestroyRegion − create or destroy regions

SYNTAX

	Region XCreateRegion(void);
	int XSetRegion(Display *display, GC gc, Region r);
	int XDestroyRegion(Region r);

ARGUMENTS


	display		Specifies the connection to the X server.
	gc		Specifies the GC.
	r		Specifies the region.

DESCRIPTION

The XCreateRegion function creates a new empty region.

The XSetRegion function sets the clip-mask in the GC to the specified region. The region is specified relative to the drawable’s origin. The resulting GC clip origin is implementation-dependent. Once it is set in the GC, the region can be destroyed.

The XDestroyRegion function deallocates the storage associated with a specified region.
