+DocStr(wxBitmap,
+"The wx.Bitmap class encapsulates the concept of a platform-dependent
+bitmap.  It can be either monochrome or colour, and either loaded from
+a file or created dynamically.  A bitmap can be selected into a memory
+device context (instance of `wx.MemoryDC`). This enables the bitmap to
+be copied to a window or memory device context using `wx.DC.Blit`, or
+to be used as a drawing surface.
+
+The BMP and XMP image file formats are supported on all platforms by
+wx.Bitmap.  Other formats are automatically loaded by `wx.Image` and
+converted to a wx.Bitmap, so any image file format supported by
+`wx.Image` can be used.
+
+:todo: Add wrappers and support for raw bitmap data access.  Can this
+       be be put into Python without losing the speed benefits of the
+       teplates and iterators in rawbmp.h?
+
+:todo: Find a way to do very efficient PIL Image <--> wx.Bitmap
+       converstions.
