XSetClipOrigin(3)		XLIB FUNCTIONS		     XSetClipOrigin(3)

NAME
       XSetClipOrigin,	XSetClipMask, XSetClipRectangles - GC convenience rou-
       tines

SYNTAX
       int XSetClipOrigin(Display *display,  GC	 gc,  int  clip_x_origin,  int
	      clip_y_origin);

       int XSetClipMask(Display	*display, GC gc, Pixmap	pixmap);

       int  XSetClipRectangles(Display *display, GC gc,	int clip_x_origin, int
	      clip_y_origin, XRectangle	rectangles[], int n, int ordering);

ARGUMENTS
       display	 Specifies the connection to the X server.

       clip_x_origin
       clip_y_origin
		 Specify the x and y coordinates of the	clip-mask origin.

       gc	 Specifies the GC.

       n	 Specifies the number of rectangles.

       ordering	 Specifies the ordering	relations on the rectangles.  You  can
		 pass Unsorted,	YSorted, YXSorted, or YXBanded.

       pixmap	 Specifies the pixmap or None.

       rectangles
		 Specifies an array of rectangles that define the clip-mask.

DESCRIPTION
       The  XSetClipOrigin  function sets the clip origin in the specified GC.
       The clip-mask origin is interpreted relative to the origin of  whatever
       destination drawable is specified in the	graphics request.

       XSetClipOrigin can generate BadAlloc and	BadGC errors.

       The XSetClipMask	function sets the clip-mask in the specified GC	to the
       specified pixmap.  If the clip-mask is set to None, the pixels are  are
       always drawn (regardless	of the clip-origin).

       XSetClipMask  can  generate BadAlloc, BadGC, BadMatch, and BadValue er-
       rors.

       The XSetClipRectangles function changes the clip-mask in	the  specified
       GC  to  the specified list of rectangles	and sets the clip origin.  The
       output is clipped to remain contained within the	rectangles.  The clip-
       origin  is  interpreted	relative to the	origin of whatever destination
       drawable	is specified in	a graphics request.  The rectangle coordinates
       are  interpreted	relative to the	clip-origin.  The rectangles should be
       nonintersecting,	or the graphics	results	will be	undefined.  Note  that
       the list	of rectangles can be empty, which effectively disables output.
       This is the opposite of passing None as	the  clip-mask	in  XCreateGC,
       XChangeGC, and XSetClipMask.

       If  known  by  the  client, ordering relations on the rectangles	can be
       specified with the ordering argument.  This may provide	faster	opera-
       tion  by	 the  server.	If  an	incorrect ordering is specified, the X
       server may generate a BadMatch error, but it is not required to do  so.
       If no error is generated, the graphics results are undefined.  Unsorted
       means the rectangles are	in arbitrary order.  YSorted  means  that  the
       rectangles  are nondecreasing in	their Y	origin.	 YXSorted additionally
       constrains YSorted order	in that	all rectangles with an equal Y	origin
       are  nondecreasing in their X origin.  YXBanded additionally constrains
       YXSorted	by requiring that, for every possible Y	scanline, all  rectan-
       gles  that  include that	scanline have an identical Y origins and Y ex-
       tents.

       XSetClipRectangles can generate BadAlloc, BadGC,	BadMatch, and BadValue
       errors.

DIAGNOSTICS
       BadAlloc	 The  server  failed  to  allocate  the	 requested resource or
		 server	memory.

       BadGC	 A value for a GContext	argument does not name a defined GCon-
		 text.

       BadMatch	 Some  argument	 or pair of arguments has the correct type and
		 range but fails to match in some other	way  required  by  the
		 request.

       BadValue	 Some numeric value falls outside the range of values accepted
		 by the	request.  Unless a specific range is specified for  an
		 argument,  the	 full  range defined by	the argument's type is
		 accepted.  Any	argument defined as a set of alternatives  can
		 generate this error.
