-Copy constructor.
+Copy constructor, uses \helpref{reference counting}{trefcount}.
+To make a real copy, you can use:
-\func{}{wxBitmap}{\param{void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
+\begin{verbatim}
+ wxBitmap newBitmap = oldBitmap.GetSubBitmap(
+ wxRect(0, 0, oldBitmap.GetWidth(), oldBitmap.GetHeight()));
+\end{verbatim}
+
+\func{}{wxBitmap}{\param{const void*}{ data}, \param{int}{ type}, \param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
Creates a bitmap from the given data which is interpreted in platform-dependent
manner.
Creates a new bitmap. A depth of -1 indicates the depth of the current screen
or visual. Some platforms only support 1 for monochrome and -1 for the current
-colour setting.
+colour setting. Beginning with version 2.5.4 of wxWidgets a depth of 32 including
+an alpha channel is supported under MSW, Mac and GTK+.
-\func{}{wxBitmap}{\param{const char**}{ bits}}
+\func{}{wxBitmap}{\param{const char* const*}{ bits}}
Creates a bitmap from XPM data.

\func{}{\destruct{wxBitmap}}{\void}
-Destroys the wxBitmap object and possibly the underlying bitmap data.
-Because reference counting is used, the bitmap may not actually be
-destroyed at this point - only when the reference count is zero will the
-data be deleted.
+Destructor.
+See \helpref{reference-counted object destruction}{refcountdestruct} for more info.
If the application omits to delete the bitmap explicitly, the bitmap will be
destroyed automatically by wxWidgets when the application exits.

the screen is used.

\func{wxBitmap\& }{operator $=$}{\param{const wxBitmap\& }{bitmap}}
-Assignment operator. This operator does not copy any data, but instead
-passes a pointer to the data in {\it bitmap} and increments a reference
-counter. It is a fast operation.
