IInkAnalysisRecognizers

Contains a collection of objects that implement the IInkAnalysisRecognizer interface and that represent the ability to recognize handwriting, objects, or gestures.

IInkAnalyzer

Provides access to layout analysis, writing and drawing classification, and handwriting recognition.

IMatchesCriteriaCallBack

Exposes a method to evaluate whether an IContextNode object meets or fails a specified criteria.
