RecognizerGuide.DrawnBox 属性

获取或设置在 Tablet 屏幕上实际绘制的书写矩形。

命名空间：  Microsoft.Ink
程序集：  Microsoft.Ink（在 Microsoft.Ink.dll 中）

语法

声明
Public Property DrawnBox As Rectangle
用法
Dim instance As RecognizerGuide
Dim value As Rectangle

value = instance.DrawnBox

instance.DrawnBox = value

public Rectangle DrawnBox { get; set; }

public:
property Rectangle DrawnBox {
    Rectangle get ();
    void set (Rectangle value);
}

/** @property */
public Rectangle get_DrawnBox()
/** @property */
public  void set_DrawnBox(Rectangle value)

public function get DrawnBox () : Rectangle
public function set DrawnBox (value : Rectangle)

属性值

类型：System.Drawing.Rectangle
在 Tablet 屏幕上实际绘制的书写矩形（相对于书写框左上方）。

备注

绘制框的线条是用于指定可书写区域的可见提示。用户通常在线条的边界内书写。

另一个矩形书写框是可实际书写的不可见框。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，它可向这些用户提供一个误差范围。使用 WritingBox 属性可以设置书写框。

书写框为识别器 指定墨迹边界。绘制框是采用墨迹空间 坐标绘制的（相对于书写框的左上方）。

示例

此示例实例化 RecognizerContext 对象，并通过创建一个新 RecognizerGuide 对象为 Guide 属性分配值。

' create a new RecognizerContext object
mRecognizerContext = New RecognizerContext()
' if the Recognizer supports LinedInput, set the Guide
If (mRecognizerContext.Recognizer.Capabilities And RecognizerCapabilities.LinedInput) <> 0 Then
    ' get the lower right corner in pixel units
    Dim lowerRight As Point = New Point(mInkOverlay.AttachedControl.Width, mInkOverlay.AttachedControl.Height)
    ' convert to ink space units
    mInkOverlay.Renderer.PixelToInkSpace(Me.CreateGraphics(), lowerRight)
    ' create Rectangles
    Dim writingBox As Rectangle = New Rectangle(0, 0, lowerRight.X, lowerRight.Y)
    Dim drawnBox As Rectangle = New Rectangle(0, 0, lowerRight.X, lowerRight.Y)
    ' shrink drawn box relative to writing box
    drawnBox.Inflate(-100, -100)
    ' create Guide with 8 rows, zero columns, and no midline
    Dim guide As RecognizerGuide = New RecognizerGuide(8, 0, 0, writingBox, drawnBox)
    mRecognizerContext.Guide = guide
End If

// create a new RecognizerContext object
mRecognizerContext = new RecognizerContext();
// if the Recognizer supports LinedInput, set the Guide
if ((mRecognizerContext.Recognizer.Capabilities & RecognizerCapabilities.LinedInput) != 0)
{
    // get the lower right corner in pixel units
    Point lowerRight = new Point(mInkOverlay.AttachedControl.Width, mInkOverlay.AttachedControl.Height);
    // convert to ink space units
    mInkOverlay.Renderer.PixelToInkSpace(this.CreateGraphics(), ref lowerRight);
    // create Rectangles
    Rectangle writingBox = new Rectangle(0, 0, lowerRight.X, lowerRight.Y);
    Rectangle drawnBox = new Rectangle(0, 0, lowerRight.X, lowerRight.Y);
    // shrink drawn box relative to writing box
    drawnBox.Inflate(-100, -100);
    // create Guide with 8 rows, zero columns, and no midline
    RecognizerGuide guide = new RecognizerGuide(8, 0, 0, writingBox, drawnBox);
    mRecognizerContext.Guide = guide;
}
