Ink Analysis Classes and Interfaces

This section contains information about the interfaces and classes used in ink analysis. The ink analysis classes and interfaces are not Automation-compliant.

Classes

Class	Description
AnalysisRegion	Implements the IAnalysisRegion interface.
InkAnalyzer	Implements the IInkAnalyzer interface.

Interfaces

Interface	Description
IAnalysisAlternate	Represents the possible handwriting recognition word matches for IContextNode objects.
IAnalysisAlternates	Contains a collection of objects that implement the IAnalysisAlternate interface and that are the result of ink analysis.
IAnalysisRegion	Exposes methods and properties for a region that represents an area of a document.
IAnalysisStatus	Represents the status of the ink analysis operation by describing whether the analysis was completed successfully and whether any warnings occurred.
IAnalysisWarning	Represents a warning or error that occurs during an ink analysis operation.
IAnalysisWarnings	Contains a collection of objects that implement the IAnalysisWarning interface and that are the result of an ink analysis operation.
IContextLink	Represents a relationship between two IContextNode objects.
IContextLinks	Contains a collection of objects that implement the IContextLink interface.
IContextNode	Represents a node in a tree of objects that are created as part of ink analysis.
IContextNodes	Contains a collection of objects that implement the IContextNode interface and that are the result of an ink analysis operation.
IInkAnalysisRecognizer	Provides access to handwriting recognizers for use with ink analysis.
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.

Return Values

Methods in the Tablet PC COM Library return values of HRESULT. Unless otherwise noted, the meanings of the HRESULT values are described in this table.

HRESULT value	Description
S_OK	Success.
E_POINTER	At least one pointer (for either an input or an output parameter) is invalid.
E_INVALIDARG	Member attempted to pass in an invalid argument.
E_INK_EXCEPTION	Exception occurred.
E_OUTOFMEMORY	System cannot allocate memory to complete the operation.
E_FAIL	Unspecified failure occurred.
E_INVALIDOPERATION	Member attempted to use an invalid operation.
TPC_E_INVALID_MODE	Member attempted to use an invalid mode.
TPC_E_INVALID_CONFIGURATION	Member attempted to use an invalid configuration.
TPC_E_INVALID_PACKET_DESCRIPTION	Member attempted to use an invalid packet description.
