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.

  narcs	    Specifies the number of arcs in the array.

  npoints   Specifies the number of points in the array.

  nrectangles
	    Specifies the number of rectangles in the array.

  points    Specifies an array of points.

  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 rectan-
	    gle.

DESCRIPTION
  The XFillRectangle and XFillRectangles functions fill the specified rectan-
  gle 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 ori-
  gin, and CoordModePrevious treats all coordinates after the first as rela-
  tive 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 infin-
  itely 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 sin-
  gle 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 argu-
	    ment, the full range defined by the argument's type is accepted.
	    Any argument defined as a set of alternatives can generate this
	    error.
