NAME
       XCopyArea, XCopyPlane - copy areas

SYNTAX
       XCopyArea(display, src, dest, gc, src_x, src_y, width, height,  dest_x,
       dest_y)
	     Display *display;
	     Drawable src, dest;
	     GC gc;
	     int src_x, src_y;
	     unsigned int width, height;
	     int dest_x, dest_y;

       XCopyPlane(display, src, dest, gc, src_x, src_y, width, height, dest_x,
       dest_y, plane)
	     Display *display;
	     Drawable src, dest;
	     GC gc;
	     int src_x, src_y;
	     unsigned int width, height;
	     int dest_x, dest_y;
	     unsigned long plane;

ARGUMENTS
       dest_x
       dest_y	 Specify the x and y coordinates, which are relative to the
		 origin of the destination rectangle and specify its upper-
		 left corner.

       display	 Specifies the connection to the X server.

       gc	 Specifies the GC.

       plane	 Specifies the bit plane.  You must set exactly one bit to 1.

       src
       dest	 Specify the source and destination rectangles to be combined.

       src_x
       src_y	 Specify the x and y coordinates, which are relative to the
		 origin of the source rectangle and specify its upper-left
		 corner.

       width
       height	 Specify the width and height, which are the dimensions of
		 both the source and destination rectangles.

DESCRIPTION
       The function combines the specified rectangle of src with the specified
       rectangle of dest.  The drawables must have the same root and depth, or
       a error results.

       If regions of the source rectangle are obscured and have not been
       retained in backing store or if regions outside the boundaries of the
       source drawable are specified, those regions are not copied.  Instead,
       the following occurs on all corresponding destination regions that are
       either visible or are retained in backing store.	 If the destination is
       a window with a background other than corresponding regions of the des‐
       tination are tiled with that background (with plane-mask of all ones
       and function).  Regardless of tiling or whether the destination is a
       window or a pixmap, if graphics-exposures is then events for all corre‐
       sponding destination regions are generated.  If graphics-exposures is
       but no events are generated, a event is generated.  Note that by
       default graphics-exposures is in new GCs.

       This function uses these GC components: function, plane-mask, subwin‐
       dow-mode, graphics-exposures, clip-x-origin, clip-y-origin, and clip-
       mask.

       can generate and errors.

       The function uses a single bit plane of the specified source rectangle
       combined with the specified GC to modify the specified rectangle of
       dest.  The drawables must have the same root but need not have the same
       depth.  If the drawables do not have the same root, a error results.
       If plane does not have exactly one bit set to 1 and the values of
       planes must be less than %2 sup n%, where n is the depth of src, a
       error results.

       Effectively, forms a pixmap of the same depth as the rectangle of dest
       and with a size specified by the source region.	It uses the fore‐
       ground/background pixels in the GC (foreground everywhere the bit plane
       in src contains a bit set to 1, background everywhere the bit plane in
       src contains a bit set to 0) and the equivalent of a protocol request
       is performed with all the same exposure semantics.  This can also be
       thought of as using the specified region of the source bit plane as a
       stipple with a fill-style of for filling a rectangular area of the des‐
       tination.

       This function uses these GC components: function, plane-mask, fore‐
       ground, background, subwindow-mode, graphics-exposures, clip-x-origin,
       clip-y-origin, and clip-mask.

       can generate and errors.

DIAGNOSTICS
       A value for a Drawable argument does not name a defined Window or
       Pixmap.

       A value for a GContext argument does not name a defined GContext.

       An	 window is used as a Drawable.

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

       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.
