XCreateRegion(3)                XLIB FUNCTIONS                XCreateRegion(3)


XCreateRegion, XSetRegion, XDestroyRegion - create or destroy regions


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


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


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.
