The drawables must have the same root and depth, or a .ZN BadMatch error results. .LP If regions of the source rectangle are obscured and have not been retained in backing store or if regions outside the boundaries of the source drawable are specified, those regions are not copied. Instead, the following occurs on all corresponding destination regions that are either visible or are retained in backing store. If the destination is a window with a background other than .ZN None , corresponding regions of the destination are tiled with that background (with plane-mask of all ones and .ZN GXcopy function). Regardless of tiling or whether the destination is a window or a pixmap, if graphics-exposures is .ZN True , then .ZN GraphicsExpose events for all corresponding destination regions are generated. If graphics-exposures is .ZN True but no .ZN GraphicsExpose events are generated, a .ZN NoExpose event is generated. Note that by default graphics-exposures is .ZN True in new GCs. .LP This function uses these GC components: function, plane-mask, subwindow-mode, graphics-exposures, clip-x-origin, clip-y-origin, and clip-mask. .LP .ZN XCopyArea can generate .ZN BadDrawable , .ZN BadGC , and .ZN BadMatch errors. .LP The .ZN XCopyPlane function uses a single bit plane of the specified source rectangle combined with the specified GC to modify the specified rectangle of dest. The drawables must have the same root but need not have the same depth. If the drawables do not have the same root, a .ZN BadMatch error results. If plane does not have exactly one bit set to 1 and the value of plane is not less than %2 sup n%, where \fIn\fP is the depth of src, a .ZN BadValue error results. .LP Effectively, .ZN XCopyPlane forms a pixmap of the same depth as the rectangle of dest and with a size specified by the source region. It uses the foreground/background pixels in the GC (foreground everywhere 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 .ZN CopyArea 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 fill-style of .ZN FillOpaqueStippled for filling a rectangular area of the destination. .LP This function uses these GC components: function, plane-mask, foreground, background, subwindow-mode, graphics-exposures, clip-x-origin, clip-y-origin, and clip-mask. .LP .ZN XCopyPlane can generate .ZN BadDrawable , .ZN BadGC , .ZN BadMatch , and .ZN BadValue errors. .SH DIAGNOSTICS .TP 1i .ZN BadDrawable A value for a Drawable argument does not name a defined Window or Pixmap. .TP 1i .ZN BadGC A value for a GContext argument does not name a defined GContext. .TP 1i .ZN BadMatch An .ZN InputOnly window is used as a Drawable. .TP 1i .ZN 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. .TP 1i .ZN 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. .SH "SEE ALSO" XClearArea(3X11) .br \fIXlib \- C Language X Interface\fP
