Remarks
To use the CMetaFileDC, create the CMetafileDC object, and then create the metafile or enhanced metafile. Enhanced metafiles are supported by all 32-bit and 64-bit Windows operating systems. These should be the default metafiles used by all modern windows applications.
Once the Metafile is closed the HMETAFILE or HENHMETADILE handle can be used to play the metafile. The handle returned by Close or CloesEnhanced should be deleted when it no longer required.
Refer to the Graphics Device Interface section of Using Win32++ for additional information on using this class.
