#define wxBITMAP(bitmapName)
+/**
+ Creates a bitmap from either application resources or embedded image data
+ in PNG format.
+
+ This macro is similar to wxBITMAP() but works with bitmap data in PNG
+ format and not BMP or XPM.
+
+ Under Windows the given @a bitmapName must be present in the application
+ resource file with the type @c RCDATA and refer to a PNG image. I.e. you
+ should have a definition similar to the following in your @c .rc file:
+ @code
+ mybitmap RCDATA "mybitmap.png"
+ @endcode
+ to be able to use @c wxBITMAP_PNG(mybitmap) in the code.
+
+ Under OS X the file with the specified name and "png" extension must be
+ present in the "Resources" subdirectory of the application bundle.
+
+ Under the other platforms, this is equivalent to wxBITMAP_PNG_FROM_DATA()
+ and so loads the image data from the array called @c bitmapName_png that
+ must exist. Notice that it @e must be an array and not a pointer as the
+ macro needs to be able to determine its size. Such an array can be produced
+ by a number of conversion programs. A very simple one is included in
+ wxWidgets distribution as @c misc/scripts/png2c.py.
+
+ Finally notice that you must register PNG image handler to be able to
+ load bitmaps from PNG data. This can be done either by calling
+ wxInitAllImageHandlers() which also registers all the other image formats
+ or including the necessary header:
+ @code
+ #include <wx/imagpng.h>
+ @endcode
+ and calling
+ @code
+ wxImage::AddHandler(new wxPNGHandler);
+ @endcode
+ in your application startup code.

+ needs to be able to determine its size. Such an array can be produced by a
