RecognizerGuide.Midline 屬性

取得或設定中線高度。中線高度是繪製方塊從基線到中線的距離。

命名空間：  Microsoft.Ink
組件：  Microsoft.Ink (在 Microsoft.Ink.dll 中)

語法

'宣告
Public Property Midline As Integer
'用途
Dim instance As RecognizerGuide
Dim value As Integer

value = instance.Midline

instance.Midline = value

public int Midline { get; set; }

public:
property int Midline {
    int get ();
    void set (int value);
}

/** @property */
public int get_Midline()
/** @property */
public  void set_Midline(int value)

public function get Midline () : int
public function set Midline (value : int)

屬性值

型別：System.Int32
輔助線的中線高度 (以 HIMETRIC 為單位)。

備註

如果中線不存在，則傳回值為 0。

範例

在這個範例中，會具現化 RecognizerContext 物件，而且會藉由建立新的 RecognizerGuide 物件指派 Guide 屬性。

' 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;
}
