.NET Library for CGM File Conversion

Question

I have been working on a utility to convert various files to PDF for easy printing/emailing. I'm trying to add support for CGM files but have not been able to find any libraries to help me do so.

Is this something that I can possibly do natively within C#? Or are there any .NET based libraries that could help me convert CGM files?

JCGM

Using IKVM you could pull in the Java JCGM library.

It has support for rendering to a Java Graphics object and no dependencies on other libraries. I'm not sure if IKVM will support all the required Swing calls but its definitely got support for some: AWT/Swing a Little Bit Less Unsupported

At a past employer, we used the LIB_CGM library from SDI quite a bit:

This was written in C - so although it isn't native .NET you should be able to use it from C# as an unmanaged extension.

Google also came up with another C implementation:

I found CGM a pain - it is one of those formats that has a lot of vendor or industry specific extensions. I was in the geophysics/seismic industry, where CGM was still being used a lot but with extensions! As CGM seems to be mainly used in industry specific applications (eg. CGM+ in the seismic industry), I suspect vendors are more interested in C applications that are readily cross-platform rather than PC-only solutions (eg. .NET). Users typically want to use their third party libraries on everything from big iron supercomputers to desktops (although we actively kept plotting functionality off the supercomputers!).
