-Copy constructor.
+Copy constructor. Note that this does not take a fresh copy of the data,
+but instead makes the internal data point to {\it bitmap}'s data. So
+changing one bitmap will change the other. 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}
-Creates a bitmap from the given data, which can be of arbitrary type.
-Windows only, I think.
+\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.
\func{}{wxBitmap}{\param{const char}{ bits[]}, \param{int}{ width}, \param{int}{ height}\\
\param{int}{ depth = 1}}
Creates a bitmap from an array of bits.
-Note that the bit depth is ignored on GTK+ and Motif. If you want to create a bitmap
-from something else than a 1-bit data array, use the \helpref{wxImage}{wximage} class.
+You should only use this function for monochrome bitmaps ({\it depth} 1) in
+portable programs: in this case the {\it bits} parameter should contain an XBM
+image.
+
+For other bit depths, the behaviour is platform dependent: under Windows, the
+data is passed without any changes to the underlying {\tt CreateBitmap()} API.
+Under other platforms, only monochrome bitmaps may be created using this
+constructor and \helpref{wxImage}{wximage} should be used for creating colour
+bitmaps from static data.
\func{}{wxBitmap}{\param{int}{ width}, \param{int}{ height}, \param{int}{ depth = -1}}
-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.
+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. 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.
Loads a bitmap from a file or resource.
+\func{}{wxBitmap}{\param{const wxImage\&}{ img}, \param{int}{ depth = -1}}
+
+Creates bitmap object from the image. This has to be done
+to actually display an image as you cannot draw an image directly on a window.
+The resulting bitmap will use the provided colour depth (or that of the
+current system if depth is -1) which entails that a colour reduction has
+to take place.
+
+When in 8-bit mode (PseudoColour mode), the GTK port will use a color cube created
+on program start-up to look up colors. This ensures a very fast conversion, but
+the image quality won't be perfect (and could be better for photo images using more
+sophisticated dithering algorithms).
+
+On Windows, if there is a palette present (set with SetPalette), it will be used when
+creating the wxBitmap (most useful in 8-bit display mode). On other platforms,
+the palette is currently ignored.
