+
+Moves the region by the specified offsets in horizontal and vertical
+directions.

Finds the union of this region and another region.
+\func{bool}{Union}{\param{const wxBitmap\&}{ bmp}}
+
+Finds the union of this region and the non-transparent pixels of a
+bitmap. Bitmap's mask is used to determine transparency. If the bitmap doesn't
+have a mask, solid rectangle of bitmap's dimensions is used.
+
+\func{bool}{Union}{\param{const wxBitmap\&}{ bmp},
+ \param{const wxColour\&}{ transColour},
+ \param{int}{ tolerance = 0}}
+
+Finds the union of this region and the non-transparent pixels of a
+bitmap. Colour to be treated as transparent is specified in the
+\arg{transColour} argument, along with an
+optional colour tolerance value.
+
\wxheading{Return value}
-TRUE if successful, FALSE otherwise.
+{\tt true} if successful, {\tt false} otherwise.
\wxheading{Remarks}
\membersection{wxRegion::Xor}\label{wxregionxor}

\wxheading{Remarks}
To use it, construct an iterator object on the stack and loop through the
regions, testing the object and incrementing the iterator at the end of the loop.
