+\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.
