The ComKit 22 libraries are made to support programmers of COM-enabled environments. They replace the IPRO libraries of the version 12 SDK. The new version is tightly integrated with the latest CSDK Engine and is based on the OmniPage Ultimate architecture. The version 22 object model is largely backward compatible with that of version 16. As the CSDK OCR engine underwent a major revision between versions 12 and 15, the current object model is not backward compatible beyond version 16.

This document summarizes the COM object hierarchy of the SDK, and the interface details for the specific objects.
