just FYI - there is a CGM extension called CGM PIP-I (Petroleum Industry
Profile ?) and an upcoming CGM PIP-II (more extensions....) that are being
put to use. In general "we" (the Petroleum industry) felt that although
CGM was such a commonly used format in our industry's applications, the
extensions were not particularly "portable" from app-to-app as pointed
to above, thus a consortium set out to put that right - creating the PIP
extensions....Zeh Graphics along with POSC (Petrotechnical Open Software Corp
- Houston Tx)
members did work on the PIP extensions and can be contacted for more info.
