RecognitionProperty Class

Defines globally unique identifiers (GUIDs) for properties that a InkRecognizerBase might support for recognition results.

Namespace:  System.Windows.Ink.AnalysisCore
Assembly:  IACore (in IACore.dll)

public sealed class RecognitionProperty

These GUIDs are available as read-only fields of this object. Use the InkRecognizerBase.GetSupportedProperties method to determine which properties are supported by a InkRecognizerBase.

Use these GUIDs to access properties of a RecognitionAlternate object by calling the GetPropertyValue method.

The following example demonstrates the RecognitionProperty class.

// Flags to hold capabilities 
    hasConfidenceLevel = false,
    hasHotPoint = false,
    hasLineMetrics = false,
    hasLineNumber = false,
    hasMaximumStrokeCount = false,
    hasPointsPerInch = false,
    hasSegmentation = false;

Guid[] myInkRecognizerCapabilityGuids = myInkRecognizer.GetSupportedProperties();

Guid myTempGuid;

for (int i = 0; i < myInkRecognizerCapabilityGuids.Length; i++)
    myTempGuid = myInkRecognizerCapabilityGuids[i];

    if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.ConfidenceLevel)
        hasConfidenceLevel = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.HotPoint)
        hasHotPoint = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.LineMetrics)
        hasLineMetrics = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.LineNumber)
        hasLineNumber = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.MaximumStrokeCount)
        hasMaximumStrokeCount = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.PointsPerInch)
        hasPointsPerInch = true;
    else if (myTempGuid == System.Windows.Ink.AnalysisCore.RecognitionProperty.Segmentation)
        hasSegmentation = true;
