Our winforms application has long allowed a "print" option which basically uses RDLC. The customer has requested that we add a feature allowing users to send the "printed" output via email. Now, we know that an EMF file is created (in the TEMP folder) as a sort of hidden byproduct of our current printing process. Seems to us we can simply grab this EMF file and attach it to a new email and the job is done. Is this the best option? Can we rely on an EMF file be opened by any Windows machine?

If you use Image.Save Method to save an image to a EMF/WMF, you get an exception ( http://msdn.microsoft.com/en-us/library/ktx83wah.aspx ) Is there another way to save the image to an EMF/WMF?
