int XFillArcs(Display *display, Drawable d, GC gc, XArc *arcs, int narcs);

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 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 an array of points.

rectangles
    Specifies 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 .

x

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

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.

and can generate and errors.

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 coordinates after the first as relative to the previous point.

Depending on the specified shape, the following occurs:

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

•   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.

•   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-stipple-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 specified 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.
