\func{}{wxRegion}{\param{size\_t}{ n}, \param{const wxPoint }{*points}, \param{int }{fillStyle = wxWINDING\_RULE}}
Constructs a region corresponding to the polygon made of {\it n} points in the
-provided array. {\it fillStyle} parameter may have values
+provided array. {\it fillStyle} parameter may have values
{\tt wxWINDING\_RULE} or {\tt wxODDEVEN\_RULE}.

+\func{}{wxRegion}{\param{const wxBitmap\&}{ bmp}}
+
+\func{}{wxRegion}{\param{const wxBitmap\&}{ bmp},

+ \param{int}{ tolerance = 0}}
+
+Constructs a region using the non-transparent pixels of a bitmap. See
+\helpref{Union}{wxregionunion} for more details.
+
\membersection{wxRegion::\destruct{wxRegion}}
On Windows, only wxOutRegion and wxInRegion are returned; a value wxInRegion then indicates that
all or some part of the region is contained in this region.
+\membersection{wxRegion::ConvertToBitmap}\label{wxregionconverttobitmap}
+
+\constfunc{wxBitmap}{ConvertToBitmap}{}
+
+Convert the region to a black and white bitmap with the white pixels
+being inside the region.

\membersection{wxRegion::Union}\label{wxregionunion}
Finds the union of this region and another region.
+\func{bool}{Union}{\param{const wxBitmap\&}{ bmp}}
+
+Finds the union of this region and the 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 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}

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.

-Returns {\tt TRUE} if there are still some rectangles; otherwise returns {\tt FALSE}.
+Returns {\tt true} if there are still some rectangles; otherwise returns {\tt false}.

\constfunc{}{operator bool}{\void}
-Returns {\tt TRUE} if there are still some rectangles; otherwise returns {\tt FALSE}.

You can use this to test the iterator object as if it were of type bool.
