RecognitionProperty 类

项目
10/28/2008

定义 InkRecognizerBase 可对识别结果支持的属性的全局唯一标识符 (GUID)。

命名空间： System.Windows.Ink.AnalysisCore
程序集： IACore（在 IACore.dll 中）

语法

声明
Public NotInheritable Class RecognitionProperty
用法
Dim instance As RecognitionProperty

public sealed class RecognitionProperty

public ref class RecognitionProperty sealed

public final class RecognitionProperty

public final class RecognitionProperty

备注

这些 GUID 作为此对象的只读字段提供。使用 InkRecognizerBase.GetSupportedProperties 方法可确定 InkRecognizerBase 支持哪些属性。

通过调用 GetPropertyValue 方法，可以使用这些 GUID 访问 RecognitionAlternate 对象的属性。

示例

下面的示例演示 RecognitionProperty 类。

' 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
    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.LineNumber Then
        hasLineNumber = True
    ElseIf myTempGuid = System.Windows.Ink.AnalysisCore.RecognitionProperty.MaximumStrokeCount Then
        hasMaximumStrokeCount = 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
End While

// 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;
    }
}
