备注
InkRecognizerGuide 通过定义两个矩形（绘制框和书写框）指定墨迹绘制区域的边界。绘制框的边界是可见的提示，而书写框的边界不可见。两种边界一起指定可以进行书写的区域。用户通常在可见线条的边界内书写。绘制框由 DrawnBoxTop、DrawnBoxLeft、DrawnBoxBottom 和 DrawnBoxRight 属性指定。这些属性仅供识别器使用。设置这些属性的操作本身不会在屏幕上绘制可见线条，而必须使用应用程序或控件来绘制可见线条。
书写框大于绘制框，当用户在绘制框的线条之外绘制墨迹时，书写框可以为用户提供一个误差范围。书写框由 WritingBoxTop、WritingBoxLeft、WritingBoxBottom 和 WritingBoxRight 属性指定。
示例
下面的示例创建一个新 InkRecognizerGuide，并将它赋给 AnalysisHintNode 的 Guide 属性。
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;
