I'm trying to load a custom font from a file using DirectWrite through SlimDX. I'm fairly certain I implemented my FontCollectionLoader and FontFileEnumerator correctly. I registered the loader with the DirectWrite factory. The problem the I keep getting is when I called SlimDX.DirectWrite.Factory.CreateCustomFontCollection I have no idea what to pass as the key and key size. Any help would be appreciated.

Well, after two days of trying, it appears that whoever implemented the FileFontEnumerator class in SlimDX didn't do so correctly. It implements the IEnumertor interface instead of the IDWriteFileEnumertor interface and that interface is not exposed through the API at all. Very disappointing.

Unless someone knows a way to turn SlimDX.DirectWrite.FontFile into SlimDX.DirectWrite.TextFormat, I guess i'll have to use a different API. *heavy sigh*
