Pen.ResetTransform 方法

定義

命名空間:

System.Drawing

組件:

System.Drawing.Common.dll

套件:

System.Drawing.Common v8.0.0

來源:

Pen.cs

將這個 Pen 的幾何轉換矩陣重設為單位矩陣。

public:
 void ResetTransform();

public void ResetTransform ();

member this.ResetTransform : unit -> unit

Public Sub ResetTransform ()

範例

下列程式代碼範例是設計來搭配 Windows Forms 使用，而且需要 PaintEventArgse，這是事件處理程序的參數Paint。 此程式碼會執行下列動作：

• 建立 Pen。

• 設定手寫筆的轉換矩陣，以 X 軸方向縮放 2 次。

• 將線條繪製到畫面。

• 將轉換矩陣重設為身分識別。

• 將第二行繪製到畫面。

public:
   void ResetTransform_Example( PaintEventArgs^ e )
   {
      
      // Create a Pen object.
      Pen^ myPen = gcnew Pen( Color::Black,3.0f );
      
      // Scale the transformation matrix of myPen.
      myPen->ScaleTransform( 2, 1 );
      
      // Draw a line with myPen.
      e->Graphics->DrawLine( myPen, 10, 0, 10, 200 );
      
      // Reset the transformation matrix of myPen to identity.
      myPen->ResetTransform();
      
      // Draw a second line with myPen.
      e->Graphics->DrawLine( myPen, 100, 0, 100, 200 );
   }

public void ResetTransform_Example(PaintEventArgs e)
{
             
    // Create a Pen object.
    Pen myPen = new Pen(Color.Black, 3);
             
    // Scale the transformation matrix of myPen.
    myPen.ScaleTransform(2, 1);
             
    // Draw a line with myPen.
    e.Graphics.DrawLine(myPen, 10, 0, 10, 200);
             
    // Reset the transformation matrix of myPen to identity.
    myPen.ResetTransform();
             
    // Draw a second line with myPen.
    e.Graphics.DrawLine(myPen, 100, 0, 100, 200);
}

Public Sub ResetTransform_Example(ByVal e As PaintEventArgs)

    ' Create a Pen object.
    Dim myPen As New Pen(Color.Black, 3)

    ' Scale the transformation matrix of myPen.
    myPen.ScaleTransform(2, 1)

    ' Draw a line with myPen.
