ARGUMENTS

       angle1    Specifies the start of the arc relative to the three-o'clock position from the
                 center, in units of degrees * 64.

       angle2    Specifies the path and extent of the arc relative to the start of the arc, in
                 units of degrees * 64.

       arcs      Specifies an array of arcs.

       d         Specifies the drawable.

       display   Specifies the connection to the X server.

       gc        Specifies the GC.

       mode      Specifies the coordinate mode.  You can pass CoordModeOrigin or
                 CoordModePrevious.

       rectangles
                 Specifies an array of rectangles.

       shape     Specifies a shape that helps the server to improve performance.  You can pass
                 Complex, Convex, or Nonconvex.

       width
       height    Specify the width and height, which are the dimensions of the rectangle to be
                 filled or the major and minor axes of the arc.

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

DESCRIPTION

       The XFillRectangle and XFillRectangles functions fill the specified rectangle or
       rectangles as if a four-point FillPolygon 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
       rectangles intersect, the intersecting pixels are drawn multiple 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.  CoordModeOrigin 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 undefined.

       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 generate this error.
