XCreateRegion(3)                                              XCreateRegion(3)




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.
