按指定因素缩放局部几何转换。此方法将缩放矩阵前面追加到转换。

public:
 void ScaleTransform(float sx, float sy);

public void ScaleTransform (float sx, float sy);

member this.ScaleTransform : single * single -> unit

Public Sub ScaleTransform (sx As Single, sy As Single)

参数

sx: Single

在 x 轴方向缩放转换所依据的因素。

sy: Single

在 y 轴方向缩放转换所依据的因素。

示例

下面的代码示例设计用于 Windows 窗体，它需要 PaintEventArgse，这是 Paint 事件处理程序的参数。该代码执行以下操作：

创建 Pen。

使用笔绘制矩形。

在 x 轴方向将笔缩放 2 次。

绘制第二个矩形来演示差异。

public:
   void ScaleTransform_Example1( PaintEventArgs^ e )
   {
      
      // Create a Pen object.
      Pen^ scalePen = gcnew Pen( Color::Black,5.0f );
      
      // Draw a rectangle with scalePen.
      e->Graphics->DrawRectangle( scalePen, 10, 10, 100, 100 );
      
      // Scale scalePen by 2X in the x-direction.
      scalePen->ScaleTransform( 2, 1 );
      
      // Draw a second rectangle with rotatePen.
      e->Graphics->DrawRectangle( scalePen, 120, 10, 100, 100 );
   }

public void ScaleTransform_Example1(PaintEventArgs e)
{
             
    // Create a Pen object.
    Pen scalePen = new Pen(Color.Black, 5);
             
    // Draw a rectangle with scalePen.
    e.Graphics.DrawRectangle(scalePen, 10, 10, 100, 100);
             
    // Scale scalePen by 2X in the x-direction.
    scalePen.ScaleTransform(2, 1);
             
    // Draw a second rectangle with rotatePen.
    e.Graphics.DrawRectangle(scalePen, 120, 10, 100, 100);
}

Public Sub ScaleTransform_Example1(ByVal e As PaintEventArgs)

    ' Create a Pen object.
    Dim scalePen As New Pen(Color.Black, 5)

    ' Draw a rectangle with scalePen.
    e.Graphics.DrawRectangle(scalePen, 10, 10, 100, 100)

    ' Scale scalePen by 2X in the x-direction.
    scalePen.ScaleTransform(2, 1)

    ' Draw a second rectangle with rotatePen.
    e.Graphics.DrawRectangle(scalePen, 120, 10, 100, 100)
End Sub
