EMFParser allows you to view windows EMF file(Enhanced Meta File) in many ways:
1. View the EMF picture itself;
2. View the EMF file header;
3. View the EMF file records in HEX mode;
4. View the EMF file records in GDI-Call mode.
I think EMFParser is easy enough to be used, so that there is no online help provided.
One outstanding feature I want to mention: You can view the EMF picture in "slow-motion". Try the scroll-bar in "The EMF" tab to experience this feature. Furthermore, using "Filter" tab, you can selective execute the GDI calls in the EMF file. Check it out and have fun!
