Possible NullPointerException
2602d24 
The EMFImageLoader is called multiple times without providing a BlendFunction. see freehep#43
This causes a NPE, in case the image is a 32 bit EMF.
I don't know if 0xFF is the correct default value, but at least this fixes the NPE.

I included a fix for this in pull request #45.

It was pretty hard to get any meaningful data from the provided file. A little more information on how to read the EMF would have been helpful.
