wxBitmap object must be created from it, and that bitmap drawn on the wxDC, using
wxDC::DrawBitmap.

Loads an image from a file.

+\func{}{wxImage}{\param{wxInputStream\& }{stream}, \param{long}{ type = wxBITMAP\_TYPE\_PNG}}
Loads an image from an input stream.

The validity of these flags depends on the platform and wxWindows configuration.
Converts the image to a platform-specific bitmap object. 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 colour depth of the current system which entails
-that a (crude) colour reduction has to take place. Especially when converting
-to 8-bit (or even less) bitmaps, the routine is slow and will reduce the
-quality of the resulting bitmap. A proper set of colour reduction methods has
-not yet been written.
+that a (crude) colour reduction has to take place. When in 8-bit mode, this
+routine will use a color cube created on program start-up to look up colors.
+Still, the image quality won't be perfect for photo images.
