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
