Detailed Description

This class defines common operations and properties that are used in the Teigha vectorization process.

Remarks
An instance of an OdGiContext subclass is normally created as a preliminary step in the vectorization process, which is to be used throughout the vectorization.

Most of the virtual functions in this class (the ones that are not pure virtual) are no-ops, serving only to define an interface.
