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.

| E_INK_EXCEPTION |
Exception occurred. |
| E_OUTOFMEMORY |
System cannot allocate memory to complete the operation. |
| E_FAIL |
Unspecified failure occurred. |
| E_INVALIDOPERATION |
