You can pass Coord-
ModeOrigin 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 X Version 11 Last change: libX11 1.3.5 1 XLIB FUNCTIONS XFillRectangle(3x11) Specifies an array of rectangles. shape Specifies a shape that helps the server to improve performance. You can pass Complex, Convex, or Nonconvex. widthheight Specify the width and height, which are the dimen-
sions of the rectangle to be filled or the major and minor axes of the arc. xy Specify the x and y coordinates, which are rela-
tive to the origin of the drawable and specify theupper-left corner of the rectangle.
DESCRIPTION
The XFillRectangle and XFillRectangles functions fill the
specified rectangle or rectangles as if a four-point FillPo-
lygon 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 andXFillRectangles do not draw a pixel more than once. If rec-
tangles intersect, the intersecting pixels are drawn multi-
ple 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. XFillPolygondoes not draw a pixel of the region more than once. Coord-
ModeOrigin treats all coordinates as relative to the origin, and CoordModePrevious treats all coordinates after the first as relative to the previous point. X Version 11 Last change: libX11 1.3.5 2 XLIB FUNCTIONS XFillRectangle(3x11) Depending on the specified shape, the following occurs:+o If shape is Complex, the path may self-intersect. Note
that contiguous coincident points in the path are nottreated as self-intersection.
+o 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.+o 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 aself-intersecting path, the graphics results are unde-
fined.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 arcand, 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. X Version 11 Last change: libX11 1.3.5 3 XLIB FUNCTIONS XFillRectangle(3x11) DIAGNOSTICS 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. Anyargument defined as a set of alternatives can gen-
erate this error.SEE ALSO
