My local government requires the use of ActiveCGM (which I believe is a form of CGM file format, version 4) for viewing technical documents.
The standard is well-documented but the idea of reading and implementing a 449 page specification sounds like a non-starter to me. Unfortunately, I can't find any decent tool for converting CGM v4 to a modern file format.
I don't mind losing active elements (such as hover) in the conversion process but I need to retain static elements (such as vectors and text) because I need to parse measurements embedded in the document.
How do I access CGM v4 in a programmatic manner, or convert it to a more recent file format?
