EMF+ - GDI+ Enhanced MetaFile format
With GDI+, Microsoft released a new metafile format called EMF+. EMF+ metafiles are much friendlier to GDI+ operations, and would be very handy things to have around, except for one fact: they didn't release any documentation on the format of EMF+ metafile records, making it impossible for developers to manipulate them.
 Microsoft has released official documentation about this format in connection to the Open Protocol Specifications. [MS-EMFPLUS]: Enhanced Metafile Format Plus Extensions Specification |
