XFillRectangle 3X11 __xorgversion__ XLIB FUNCTIONS XFillRectangle XFillRectangles XFillPolygon XFillArc XFillArcs fill rectangles, polygons, or arcs int XFillRectangle ( Display *display , Drawable d , GC gc , int x , int y , unsigned int width , unsigned int height ); int XFillRectangles ( Display *display , Drawable d , GC gc , XRectangle *rectangles , int nrectangles ); int XFillPolygon ( Display *display , Drawable d , GC gc , XPoint *points , int npoints , int shape , int mode ); int XFillArc ( Display *display , Drawable d , GC gc , int x , int y , unsigned int width , unsigned int height , int angle1 , int angle2 ); int XFillArcs ( Display *display , Drawable d , GC gc , XArc *arcs , int narcs ); 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 . or the major and minor axes of the arc width height Specify the width and height, which are the dimensions of the rectangle to be filled. and specify the upper-left corner of the rectangle x y Specify the x and y coordinates, which are relative to the origin of the drawable. 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.  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.
