10 int XFillRectangle(Display *display, Drawable d, GC gc, int x, int y,
11 unsigned int width, unsigned int height);
12 int XFillRectangles(Display *display, Drawable d, GC gc, XRectangle
14 *rectangles, int nrectangles);
15 int XFillPolygon(Display *display, Drawable d, GC gc, XPoint *points,
17 int npoints, int shape, int mode);
18 int XFillArc(Display *display, Drawable d, GC gc, int x, int y, un‐
20 signed int width, unsigned int height, int angle1, int angle2);
21 int XFillArcs(Display *display, Drawable d, GC gc, XArc *arcs, int
23 narcs);
24
26 angle1 Specifies the start of the arc relative to the three-o'clock
27 position from the center, in units of degrees * 64.
28 angle2 Specifies the path and extent of the arc relative to the
30 start of the arc, in units of degrees * 64.
31 arcs Specifies an array of arcs.
33 d Specifies the drawable.
35 display Specifies the connection to the X server.
37 gc Specifies the GC.
39 mode Specifies the coordinate mode. You can pass CoordModeOrigin
41 or CoordModePrevious.
42 narcs Specifies the number of arcs in the array.
44 npoints Specifies the number of points in the array.
46 nrectangles
48 Specifies the number of rectangles in the array.
49 points Specifies an array of points.
51 rectangles
53 Specifies an array of rectangles.
54 shape Specifies a shape that helps the server to improve perfor‐
56 mance. You can pass Complex, Convex, or Nonconvex.
57 width
59 height Specify the width and height, which are the dimensions of the
60 rectangle to be filled or the major and minor axes of the
61 arc.
62 x
64 y Specify the x and y coordinates, which are relative to the
65 origin of the drawable and specify the upper-left corner of
66 the rectangle.
67
69 The XFillRectangle and XFillRectangles functions fill the specified
70 rectangle or rectangles as if a four-point FillPolygon protocol request
71 were specified for each rectangle:
72 [x,y] [x+width,y] [x+width,y+height] [x,y+height]
74 Each function uses the x and y coordinates, width and height dimen‐
76 sions, and GC you specify.
77 XFillRectangles fills the rectangles in the order listed in the array.
79 For any given rectangle, XFillRectangle and XFillRectangles do not draw
80 a pixel more than once. If rectangles intersect, the intersecting pix‐
81 els are drawn multiple times.
82 Both functions use these GC components: function, plane-mask, fill-
84 style, subwindow-mode, clip-x-origin, clip-y-origin, and clip-mask.
85 They also use these GC mode-dependent components: foreground, back‐
86 ground, tile, stipple, tile-stipple-x-origin, and tile-stipple-y-ori‐
87 gin.
88 XFillRectangle and XFillRectangles can generate BadDrawable, BadGC, and
90 BadMatch errors.
91 XFillPolygon fills the region closed by the specified path. The path
93 is closed automatically if the last point in the list does not coincide
94 with the first point. XFillPolygon does not draw a pixel of the region
95 more than once. CoordModeOrigin treats all coordinates as relative to
96 the origin, and CoordModePrevious treats all coordinates after the
97 first as relative to the previous point.
98 Depending on the specified shape, the following occurs:
100 • If shape is Complex, the path may self-intersect. Note that con‐
102 tiguous coincident points in the path are not treated as self-in‐
103 tersection.
104 • If shape is Convex, for every pair of points inside the polygon,
106 the line segment connecting them does not intersect the path. If
107 known by the client, specifying Convex can improve performance.
108 If you specify Convex for a path that is not convex, the graphics
109 results are undefined.
110 • If shape is Nonconvex, the path does not self-intersect, but the
112 shape is not wholly convex. If known by the client, specifying
113 Nonconvex instead of Complex may improve performance. If you
114 specify Nonconvex for a self-intersecting path, the graphics re‐
115 sults are undefined.
116 The fill-rule of the GC controls the filling behavior of self-inter‐
118 secting polygons.
119 This function uses these GC components: function, plane-mask, fill-
121 style, fill-rule, subwindow-mode, clip-x-origin, clip-y-origin, and
122 clip-mask. It also uses these GC mode-dependent components: fore‐
123 ground, background, tile, stipple, tile-stipple-x-origin, and tile-
124 stipple-y-origin.
125 XFillPolygon can generate BadDrawable, BadGC, BadMatch, and BadValue
127 errors.
128 For each arc, XFillArc or XFillArcs fills the region closed by the in‐
130 finitely thin path described by the specified arc and, depending on the
131 arc-mode specified in the GC, one or two line segments. For ArcChord,
132 the single line segment joining the endpoints of the arc is used. For
133 ArcPieSlice, the two line segments joining the endpoints of the arc
134 with the center point are used. XFillArcs fills the arcs in the order
135 listed in the array. For any given arc, XFillArc and XFillArcs do not
136 draw a pixel more than once. If regions intersect, the intersecting
137 pixels are drawn multiple times.
138 Both functions use these GC components: function, plane-mask, fill-
140 style, arc-mode, subwindow-mode, clip-x-origin, clip-y-origin, and
141 clip-mask. They also use these GC mode-dependent components: fore‐
142 ground, background, tile, stipple, tile-stipple-x-origin, and tile-
143 stipple-y-origin.
144 XFillArc and XFillArcs can generate BadDrawable, BadGC, and BadMatch
146 errors.
147
149 BadDrawable
150 A value for a Drawable argument does not name a defined Win‐
151 dow or Pixmap.
152 BadGC A value for a GContext argument does not name a defined GCon‐
154 text.
155 BadMatch An InputOnly window is used as a Drawable.
157 BadMatch Some argument or pair of arguments has the correct type and
159 range but fails to match in some other way required by the
160 request.
161 BadValue Some numeric value falls outside the range of values accepted
163 by the request. Unless a specific range is specified for an
164 argument, the full range defined by the argument's type is
165 accepted. Any argument defined as a set of alternatives can
166 generate this error.
