SYNTAX

Region XCreateRegion() XSetRegion(display, gc, r) Display *display; GC gc; Region r; XDestroyRegion(r) 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 asso- ciated with a specified region.
