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 a pointer to 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 or
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 a pointer to an array of points.
rectangles
Specifies a pointer to an array of rectangles.
shape Specifies a shape that helps the server to improve performance. You can pass or
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 rec-
tangle.
Description
The and functions fill the specified rectangle or rectangles as if a four-point 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.
fills the rectangles in the order listed in the array. For any given rectangle, and 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.

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. does not draw a pixel of the region more than once. treats all coordinates as relative to the origin, and treats all coordi-
nates after the first as relative to the previous point.
Depending on the specified shape, the following occurs:
o If shape is the path may self-intersect. Note that contiguous coincident points in the path are not treated as self-intersection.
o If shape is for every pair of points inside the polygon, the line segment connecting them does not intersect the path. If known by
the client, specifying can improve performance. If you specify for a path that is not convex, the graphics results are undefined.
o If shape is the path does not self-intersect, but the shape is not wholly convex. If known by the client, specifying instead of may
improve performance. If you specify 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-stip-
ple-y-origin.
can generate and errors.
For each arc, or fills the region closed by the infinitely thin path described by the specified arc and, depending on the arc-mode speci-
fied in the GC, one or two line segments. For the single line segment joining the endpoints of the arc is used. For the two line segments
joining the endpoints of the arc with the center point are used. fills the arcs in the order listed in the array. For any given arc, and
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.

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.
