+You should only use this function for monochrome bitmaps ({\it depth} 1) in

+For other bit depths, the behaviour is platform dependent: under Windows, the

+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.
