Property Value

The left coordinate for the invisible writing area of the InkRecognizerGuide in which writing can occur.

Remarks

The writing box provides a margin of error to users who write outside the drawn box. Use the DrawnBoxTop, DrawnBoxLeft, DrawnBoxBottom, and DrawnBoxRight properties to set the drawn box.

The WritingBoxLeft property throws an ArgumentOutOfRangeException if you try to set it to a value less that AnalysisRegion.MinXY or greater than AnalysisRegion.MaxXY.

Example

The following sets all of the values in the InkRecognizerGuide simultaneously.

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

theGuide.Rows = 1
theGuide.Columns = 0
theGuide.Midline = midline

theGuide.WritingBoxLeft = guideBoxLeft - WRITINGBOXMARGIN
theGuide.WritingBoxTop = guideBoxTop - WRITINGBOXMARGIN
theGuide.WritingBoxRight = guideBoxRight + WRITINGBOXMARGIN
theGuide.WritingBoxBottom = guideBoxBottom + WRITINGBOXMARGIN

theGuide.DrawnBoxLeft = guideBoxLeft
theGuide.DrawnBoxTop = guideBoxTop
theGuide.DrawnBoxRight = guideBoxRight
theGuide.DrawnBoxBottom = guideBoxBottom

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;

theGuide.Rows = 1;
theGuide.Columns = 0;
theGuide.Midline = midline;

theGuide.WritingBoxLeft = guideBoxLeft - WRITINGBOXMARGIN;
theGuide.WritingBoxTop = guideBoxTop - WRITINGBOXMARGIN;
theGuide.WritingBoxRight = guideBoxRight + WRITINGBOXMARGIN;
theGuide.WritingBoxBottom = guideBoxBottom + WRITINGBOXMARGIN;

theGuide.DrawnBoxLeft = guideBoxLeft;
theGuide.DrawnBoxTop = guideBoxTop;
theGuide.DrawnBoxRight = guideBoxRight;
theGuide.DrawnBoxBottom = guideBoxBottom;
