public:
void Scale(float scaleX, float scaleY, System::Drawing::Drawing2D::MatrixOrder order);
public void Scale (float scaleX, float scaleY, System.Drawing.Drawing2D.MatrixOrder order);
member this.Scale : single * single * System.Drawing.Drawing2D.MatrixOrder -> unit
Public Sub Scale (scaleX As Single, scaleY As Single, order As MatrixOrder)
参数
- order
- MatrixOrder
一个 MatrixOrder,指定将缩放向量应用于此 Matrix的顺序(追加或追加)。
示例
下面的代码示例旨在与 Windows 窗体一起使用,它需要 PaintEventArgse
Paint 事件对象。 该代码执行以下操作:
在应用缩放转换(蓝色矩形)之前,将矩形绘制到屏幕。
创建矩阵并将其缩放为 x 轴中的 3,在 y 轴中创建 2。
将此矩阵转换应用于矩形。
将转换后的矩形绘制到屏幕(红色矩形)。
请注意,红色矩形已按 x 轴中的 3 因子缩放,在 y 轴中缩放 2,包括矩形的左上角(矩形的起点)。
public:
void ScaleExample( PaintEventArgs^ e )

// Create a matrix and scale it.

myMatrix->Scale( 3, 2, MatrixOrder::Append );
