XFillPolygon(display, d, gc, points, npoints, shape, mode)
      Display *display;
      Drawable d;
      GC gc;
      XPoint *points;
      int npoints;
      int shape;
      int mode;


display Specifies the connection to the X server.
d Specifies the drawable.
gc Specifies the GC.
points Specifies an array of points.
npoints Specifies the number of points in the array.
shape Specifies a shape that helps the server to improve performance. You can pass Complex, Convex, or Nonconvex.
mode Specifies the coordinate mode. You can pass CoordModeOrigin or CoordModePrevious.


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:

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.


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.
