     shape     Specifies a shape that helps the server to improve
               performance. You can pass Complex, Convex, or Non-
               convex. or the major and minor axes of the arc

     width
     height    Specify the width and height, which are the dimen-
               sions of the rectangle to be filled. and specify
               the upper-left corner of the rectangle

     x
     y         Specify the x and y coordinates, which are rela-
               tive to the origin of the drawable.

DESCRIPTION

     The XFillRectangle and XFillRectangles functions fill the
     specified rectangle or rectangles as if a four-point FillPo-
     lygon protocol request were specified for each rectangle:

     [x,y] [x+width,y] [x+width,y+height] [x,y+height]

     Each function uses the x and y coordinates, width and height
     dimensions, and GC you specify.

     XFillRectangles fills the rectangles in the order listed in
     the array. For any given rectangle, XFillRectangle and
     XFillRectangles do not draw a pixel more than once. If rec-
     tangles intersect, the intersecting pixels are drawn multi-
     ple times.

     Both functions use these GC components: function, plane-
     mask, fill-style, subwindow-mode, clip-x-origin, clip-y-
     origin, and clip-mask. They also use these GC mode-dependent
     components: foreground, background, tile, stipple, tile-
     stipple-x-origin, and tile-stipple-y-origin.

     XFillRectangle and XFillRectangles can generate BadDrawable,
     BadGC, and BadMatch errors.

     XFillPolygon fills the region closed by the specified path.
     The path is closed automatically if the last point in the
     list does not coincide with the first point. XFillPolygon
     does not draw a pixel of the region more than once. CoordMo-
     deOrigin treats all coordinates as relative to the origin,
     and CoordModePrevious treats all coordinates after the first
     as relative to the previous point.

     Depending on the specified shape, the following occurs:

     +    If shape is Complex, the path may self-intersect. Note
          that contiguous coincident points in the path are not
          treated as self-intersection.

     +    If shape is Convex, for every pair of points inside the
          polygon, the line segment connecting them does not
          intersect the path. If known by the client, specifying
          Convex can improve performance. If you specify Convex
          for a path that is not convex, the graphics results are
          undefined.

     +    If shape is Nonconvex, the path does not self-
          intersect, but the shape is not wholly convex. If known
          by the client, specifying Nonconvex instead of Complex
          may improve performance. If you specify Nonconvex for a
          self-intersecting path, the graphics results are unde-
          fined.

     The fill-rule of the GC controls the filling behavior of
     self-intersecting polygons.

     This function uses these GC components: function, plane-
     mask, fill-style, fill-rule, subwindow-mode, clip-x-origin,
     clip-y-origin, and clip-mask. It also uses these GC mode-
     dependent components: foreground, background, tile, stipple,
     tile-stipple-x-origin, and tile-stipple-y-origin.

     XFillPolygon can generate BadDrawable, BadGC, BadMatch, and
     BadValue errors.

     For each arc, XFillArc or XFillArcs fills the region closed
     by the infinitely thin path described by the specified arc
     and, depending on the arc-mode specified in the GC, one or
     two line segments. For ArcChord, the single line segment
     joining the endpoints of the arc is used. For ArcPieSlice,
     the two line segments joining the endpoints of the arc with
     the center point are used. XFillArcs fills the arcs in the
     order listed in the array. For any given arc, XFillArc and
     XFillArcs do not draw a pixel more than once. If regions
     intersect, the intersecting pixels are drawn multiple times.

     Both functions use these GC components: function, plane-
     mask, fill-style, arc-mode, subwindow-mode, clip-x-origin,
     clip-y-origin, and clip-mask. They also use these GC mode-
     dependent components: foreground, background, tile, stipple,
     tile-stipple-x-origin, and tile-stipple-y-origin.

     XFillArc and XFillArcs can generate BadDrawable, BadGC, and
     BadMatch errors.

DIAGNOSTICS

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

     BadGC     A value for a GContext argument does not name a

               defined GContext.

     BadMatch  An InputOnly window is used as a Drawable.

     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 gen-
               erate this error.
