Property Value

The recognizer guide that the InkAnalyzer uses to analyze ink within this area. The default is an InkRecognizerGuide where all of its properties are set to 0.

Remarks

Note

If the System.Windows.Ink.InkRecognizer that the InkAnalyzer uses for handwriting recognition does not support guides, the InkAnalyzer ignores the guide. For more information about the capabilities that an InkRecognizer supports, see InkRecognizer.Capabilities.

All coordinates of the RecognizerGuide are in ink-space coordinates and are relative to the top left corner of the hint. For a global hint, the guide is not translated; it uses the Ink object's coordinate system. For more information about using a guide to improve handwriting recognition, see RecognizerGuide.

During analysis, if the ink recognizer applied to the strokes does not support a guide, the ink analyzer generates an AnalysisWarning with its WarningCode property set to the System.Windows.Ink.AnalysisWarningCode value of GuideNotSupported.

To remove a guide from a hint, call the ClearGuide method, or the hint's RemovePropertyData method with propertyDataId set to PropertyGuidsForAnalysisHints.Guide.

Example

This example creates an AnalysisHintNode, theAnalysisHint, for the InkAnalyzer, theInkAnalyzerWithHint, and makes theAnalysisHint a global hint. It then sets the Guide and Name properties on the hint.

Dim guideBoxTop As Double = 0
Dim guideBoxBottom As Double = 50
Dim guideBoxLeft As Double = 0
Dim guideBoxRight As Double = 600

Dim WRITINGBOXMARGIN As Integer = 10

' Find the midline of the guide box.
Dim midline As Double = (guideBoxBottom - guideBoxTop) / 2 + guideBoxTop

' Add a new, global analysis hint to theInkAnalyzerWithHint.
Dim theAnalysisHint As AnalysisHintNode = Me.theInkAnalyzerWithHint.CreateAnalysisHint()
theAnalysisHint.Location.MakeInfinite()

' Create an InkRecognizerGuide with the writing box
' slightly larger than the drawing box.
Dim theGuide As New InkRecognizerGuide(1, 0, midline, _
    guideBoxLeft - WRITINGBOXMARGIN, guideBoxTop - WRITINGBOXMARGIN, _
    guideBoxRight + WRITINGBOXMARGIN, guideBoxBottom + WRITINGBOXMARGIN, _
    guideBoxLeft, guideBoxTop, guideBoxRight, guideBoxBottom)

theAnalysisHint.Guide = theGuide
theAnalysisHint.Name = "Recognizer Guide"

double guideBoxTop = 0;
double guideBoxBottom = 50;
double guideBoxLeft = 0;
double guideBoxRight = 600;

const int WRITINGBOXMARGIN = 10;

// Find the midline of the guide box.
double midline = (guideBoxBottom - guideBoxTop) / 2 + guideBoxTop;

// Add a new, global analysis hint to theInkAnalyzerWithHint.
AnalysisHintNode theAnalysisHint =
    this.theInkAnalyzerWithHint.CreateAnalysisHint();
theAnalysisHint.Location.MakeInfinite();

// Create an InkRecognizerGuide with the writing box
// slightly larger than the drawing box.
InkRecognizerGuide theGuide = new InkRecognizerGuide(1, 0, midline, 
    guideBoxLeft - WRITINGBOXMARGIN, guideBoxTop - WRITINGBOXMARGIN, 
    guideBoxRight + WRITINGBOXMARGIN, guideBoxBottom + WRITINGBOXMARGIN,
    guideBoxLeft, guideBoxTop, guideBoxRight, guideBoxBottom);

theAnalysisHint.Guide = theGuide;
theAnalysisHint.Name = "Recognizer Guide";
