the image quality won't be perfect (and could be better for photo images using more
sophisticated dithering algorithms).

-\overview{Overview}{wxbitmapoverview}
-
-This is the base class for implementing bitmap file loading/saving, and bitmap creation from data.
-It is used within wxBitmap and is not normally seen by the application.
-
-If you wish to extend the capabilities of wxBitmap, derive a class from wxBitmapHandler
-and add the handler using \helpref{wxBitmap::AddHandler}{wxbitmapaddhandler} in your
-application initialisation.
