RecognitionProperty Constants

RecognitionProperty Constants

Defines values that specify the properties of a recognition alternate. The Tablet PC application programming interface (API) uses globally unique identifiers (GUIDs) to identify packet properties, which in Automation are constant strings.

C++

In C++, you can access these constants in the Msinkaut.h header file, which is located in the <systemdrive>:\Program Files\Microsoft Tablet PC Platform SDK\Include directory if you installed the SDK in the default ___location.

Note: In C++, these constants are WCHARs, not BSTRs. Convert them into BSTRs before use. For more information about the BSTR data type, see Using the Automation Library.

Visual Basic 6.0

In Microsoft® Visual Basic® 6.0, these constants are defined in the InkConstants.bas file, which is located in the <systemdrive>:\Program Files\Microsoft Tablet PC Platform SDK\Include directory if you installed the SDK in the default ___location.

Constants

The following table lists the available recognition alternate property globally unique identifier (GUID) fields. Use these GUIDs to access properties of a IInkRecognitionAlternate object by calling the GetPropertyValue method.

C++ Name Visual Basic 6.0 Name Definition
INKRECOGNITIONPROPERTY_LINENUMBER LineNumber The GUID that identifies the property for the line number of the IInkRecognitionAlternate object.

LineNumber specifies the alternates with a particular line number.

Note: This field is not supported for recognizers of East Asian characters.
INKRECOGNITIONPROPERTY_SEGMENTATION Segmentation The GUID that identifies the property for the segmentation of the IInkRecognitionAlternate object.

Segmentation specifies the basic ink fragment or unit that the recognizer uses to produce a recognition result.

Note: Not implemented.
INKRECOGNITIONPROPERTY_HOTPOINT HotPoint The GUID that identifies the property for the recognition hot point of the IInkRecognitionAlternate object.
INKRECOGNITIONPROPERTY_MAXIMUMSTROKECOUNT MaximumStrokeCount The GUID that identifies the property for the maximum stroke count of the recognition result for the IInkRecognitionAlternate object.

Note: Not implemented.
INKRECOGNITIONPROPERTY_POINTSPERINCH PointsPerInch The GUID that identifies the property for the points-per-inch metric of the IInkRecognitionAlternate object.

Note: Not implemented.
INKRECOGNITIONPROPERTY_CONFIDENCELEVEL ConfidenceLevel The GUID that identifies the property for the level of confidence that the recognizer has in the recognition result.

Note: Confidence evaluation is available only for United States English and all gesture recognizers in the current release of Microsoft Windows® XP Tablet PC Edition. Methods that provide the confidence property for any other recognizer return E_NOTIMPL.
INKRECOGNITIONPROPERTY_LINEMETRICS LineMetrics The GUID that identifies the property for the line metrics of the IInkRecognitionAlternate object, which is the line for which to retrieve metrics.
