RecognitionProperty Class

Článek
12/08/2012

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)

Syntax

'Declaration
Public NotInheritable Class RecognitionProperty
'Usage
Dim instance As RecognitionProperty

public sealed class RecognitionProperty

public ref class RecognitionProperty sealed

public final class RecognitionProperty

Remarks

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.

Examples

The following example demonstrates the RecognitionProperty class.

' Flags to hold capabilities 
Dim hasConfidenceLevel As Boolean = False 
Dim hasHotPoint As Boolean = False 
Dim hasLineMetrics As Boolean = False 
Dim hasLineNumber As Boolean = False 
Dim hasMaximumStrokeCount As Boolean = False 
Dim hasPointsPerInch As Boolean = False 
Dim hasSegmentation As Boolean = False 

Dim myInkRecognizerCapabilityGuids() As Guid = myInkRecognizer.GetSupportedProperties()

Dim myTempGuid As Guid = Nothing 

Dim i As Integer = 0

While i < myInkRecognizerCapabilityGuids.Length
    myTempGuid = myInkRecognizerCapabilityGuids(i)

    If myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.ConfidenceLevel Then
        hasConfidenceLevel = True 
    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.HotPoint Then
        hasHotPoint = True 
    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.LineMetrics Then
        hasLineMetrics = True

        hasLineNumber = True

    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.PointsPerInch Then
        hasPointsPerInch = True 
    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.Segmentation Then
        hasSegmentation = True 
    End If

    i = i + 1

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

    {
