It uses the foreground/background pixels in the GC (foregroundeverywhere the bit plane in src contains a bit set to 1,background everywhere the bit plane in src contains a bit set to 0)and the equivalent of a <B><A HREF="../appendix/a.html#CopyArea">CopyArea</A></B>protocol request is performed with all the same exposure semantics.This can also be thought of as using the specified region of the source bit plane as a stipple with a <A HREF="../GC/manipulating.html#fill-style">fill-style</A> of<B>FillOpaqueStippled</B>for filling a rectangular area of the destination.<P>This function uses 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#foreground">foreground</A>,<A HREF="../GC/manipulating.html#background">background</A>,<A HREF="../GC/manipulating.html#subwindow-mode">subwindow-mode</A>,<A HREF="../GC/manipulating.html#graphics-exposure">graphics-exposures</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>.<P><B>XCopyPlane()</B>can generate<B>BadDrawable</B>,<B>BadGC</B>,<B>BadMatch</B>,and <B>BadValue</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. <TR><TD><B>BadValue</B><TD> Some numeric value falls outside the range of values accepted by the request.
