CM93 Format Documentation ? Code Library ?

Just started a new project for making VTS software and I'd like to make my own CM93 viewer to have total control over the display. Ideally I'd like to make an open C# .NET code library for reading and displaying CM93 charts and then use it as part of our commercial software.

I understand that OpenCPN can read CM93 charts? I'm having trouble finding documentation anywhere on the actual binary format of those chart files. Does anyone know where that can be found? Can't seem to find it on Jeppesen's site.

Are there any other open source code libraries for reading CM93?

Re: CM93 Format documentation? Code library?

ngermain...
I'm afraid that all I can suggest is you start reading at SourceForge - opencpn/opencpn/blob - include/cm93.h to get a picture about the CM93 implementation in OpenCPN. I don't know about any documentation on this subject.
Note that OpenCPN reads just CM93v2 charts - not available publicly from Jeppesen anymore. I suppose Jeppesen has some documentation about their proprietary formats (perhaps even SDK) and should have no problem providing it to another commercial entity, probably for fee and under more or less restrictive conditions, just contact them directly. Some general info at Jeppesen Norway - C-MAP Professional Information

Thanks for the response. I guess OpenCPN won't be that much help then, I really need v3 charts. I actually do have the SDK from Jeppesen but it seems pretty closed, no source and no format documentation. And no, the SDK is *far* from free.
