For <B>ArcChord</B> , the single line segment joining the endpoints of the arc is used. For <B>ArcPieSlice</B> ,the two line segments joining the endpoints of the arc with the centerpoint are used. For any given arc, .PN XFillArcdoes not draw a pixel more than once. If regions intersect, the intersecting pixels are drawn multiple times.<P>Both functions use these GC components: <A HREF="../../GC/manipulating.html#function">function</A>,<A HREF="../../GC/manipulating.html#plane-mask">plane-mask</A>,<A HREF="../../GC/manipulating.html#fill-style">fill-style</A>,<A HREF="../../GC/manipulating.html#arc-mode">arc-mode</A>,<A HREF="../../GC/manipulating.html#subwindow-mode">subwindow-mode</A>,<A HREF="../../GC/manipulating.html#clip-mask">clip-x-origin</A>, <A HREF="../../GC/manipulating.html#clip-mask">clip-y-origin</A>,and<A HREF="../../GC/manipulating.html#clip-mask">clip-mask</A>.They also use these GC mode-dependent components: <A HREF="../../GC/manipulating.html#foreground">foreground</A>,<A HREF="../../GC/manipulating.html#background">background</A>,<A HREF="../../GC/manipulating.html#tile">tile</A>,<A HREF="../../GC/manipulating.html#stipple">stipple</A>,<A HREF="../../GC/manipulating.html#tile">tile-stipple-x-origin</A>, and<A HREF="../../GC/manipulating.html#tile">tile-stipple-y-origin</A>.<P><B>XFillArc()</B>can generate<B>BadDrawable</B> ,<B>BadGC</B> ,and<B>BadMatch</B> errors.<H2>Diagnostics</H2><TABLE><TR><TD><B>BadDrawable</B><TD>A value for a Drawable argument does not name a defined Window or Pixmap.<TR><TD><B>BadGC</B><TD>A value for a <B><A HREF="../GContext.html">GContext</A></B> argument does not name a defined <B><A HREF="../GContext.html">GContext</A></B>.<TR><TD><B>BadMatch</B><TD>An<B><A HREF="../window/create.html#InputClass">InputOnly</A></B>window is used as a Drawable.<TR><TD><B>BadMatch</B><TD>Some argument or pair of arguments has the correct type and range but fails to match in some other way required by the request.</TABLE><H2>See also</H2><B><A HREF="../drawing/XDrawArc.html">XDrawArc()</A></B>,<B><A HREF="../drawing/XDrawPoint.html">XDrawPoint()</A></B>,<B><A HREF="../drawing/XDrawRectangle.html">XDrawRectangle()</A></B><B><A HREF="XFillArcs.html">XFillArcs()</A></B>,<B><A HREF="XFillPolygon.html">XFillPolygon()</A></B>,<B><A HREF="XFillRectangle.html">XFillRectangle()</A></B>,<B><A HREF="XFillRectangles.html">XFillRectangles()</A></B>,"<A HREF="arcs.html">Filling Single and Multiple Arcs</A>".<HR><ADDRESS><A HREF="http://tronche.com/">Christophe Tronche</A>, <A HREF="mailto:ch.tronche@computer.org">ch.tronche@computer.org</A></ADDRESS></BODY></HTML>⌨️ 快捷键说明
