按指定量放大 Rectangle 结构。

重载

Inflate(Size)	将此 Rectangle 放大指定金额。
Inflate(Int32, Int32)	将此 Rectangle 放大指定金额。
Inflate(Rectangle, Int32, Int32)	创建并返回指定 Rectangle 结构的放大副本。副本按指定的金额放大。原始 Rectangle 结构保持不变。

将此 Rectangle 放大指定金额。

public:
 void Inflate(System::Drawing::Size size);

public void Inflate(System.Drawing.Size size);

member this.Inflate : System.Drawing.Size -> unit

Public Sub Inflate (size As Size)

参数

size: Size

放大此矩形的量。

示例

下面的示例设计用于 Windows 窗体，它需要 PaintEventArgse，这是 Paint 事件处理程序的参数。该代码将创建一个 Rectangle，并在两个轴中将其放大 50 个单位。矩形在通货膨胀（黑色）和通货膨胀后（红色）之前绘制为屏幕。

public:
   void RectangleInflateTest2( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rect = Rectangle(100,100,50,50);

      // Draw the uninflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Black, rect );

      // Set up the inflate size.
      System::Drawing::Size inflateSize = System::Drawing::Size( 50, 50 );

      // Call Inflate.
      rect.Inflate( inflateSize );

      // Draw the inflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Red, rect );
   }

public void RectangleInflateTest2(PaintEventArgs e)
{
             
    // Create a rectangle.
    Rectangle rect = new Rectangle(100, 100, 50, 50);
             
    // Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect);
             
    // Set up the inflate size.
    Size inflateSize = new Size(50, 50);
             
    // Call Inflate.
    rect.Inflate(inflateSize);
             
    // Draw the inflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect);
}

Public Sub RectangleInflateTest2(ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rect As New Rectangle(100, 100, 50, 50)

    ' Draw the uninflated rect to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect)

    ' Set up the inflate size.
    Dim inflateSize As New Size(50, 50)

    ' Call Inflate.
    rect.Inflate(inflateSize)

    ' Draw the inflated rect to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect)
End Sub

注解

此方法放大此矩形，而不是该矩形的副本。矩形沿轴向两个方向放大。例如，如果在 x 轴中放大 50 到 50 个矩形，则生成的矩形长 150 单位（原始 50，负方向为 50，加方向为 50），并保留矩形几何中心 50。

适用于

Inflate(Int32, Int32)

将此 Rectangle 放大指定金额。

public:
 void Inflate(int width, int height);

public void Inflate(int width, int height);

member this.Inflate : int * int -> unit

Public Sub Inflate (width As Integer, height As Integer)

参数

width: Int32

水平膨胀此 Rectangle 量。

height: Int32

垂直膨胀此 Rectangle 量。

示例

以下示例创建一个 Rectangle 结构，并在 x 轴方向将其放大 100 个单位：

public:
   void RectangleInflateTest3( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rect = Rectangle(100,100,50,50);

      // Draw the uninflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Black, rect );

      // Call Inflate.
      rect.Inflate( 50, 50 );

      // Draw the inflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Red, rect );
   }

public void RectangleInflateTest3(PaintEventArgs e)
{
             
    // Create a rectangle.
    Rectangle rect = new Rectangle(100, 100, 50, 50);
             
    // Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect);
             
    // Call Inflate.
    rect.Inflate(50, 50);
             
    // Draw the inflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect);
}

Public Sub RectangleInflateTest3(ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rect As New Rectangle(100, 100, 50, 50)

    ' Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect)

    ' Call Inflate.
    rect.Inflate(50, 50)

    ' Draw the inflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect)
End Sub

注解

如果 x 或 y 为负值，则 Rectangle 结构将按相应的方向平展。

示例

下面的示例设计用于 Windows 窗体，它需要 PaintEventArgse，这是 Paint 事件处理程序的参数。该代码将创建一个 Rectangle，并在两个轴中将其放大 50 个单位。请注意，生成的矩形（红色）是两个轴中的 150 个单位。

public:
   void RectangleInflateTest( PaintEventArgs^ e )
   {
      // Create a rectangle.
      Rectangle rect = Rectangle(100,100,50,50);

      // Draw the uninflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Black, rect );

      // Call Inflate.
      Rectangle rect2 = Rectangle::Inflate( rect, 50, 50 );

      // Draw the inflated rectangle to screen.
      e->Graphics->DrawRectangle( Pens::Red, rect2 );
   }

public void RectangleInflateTest(PaintEventArgs e)
{
             
    // Create a rectangle.
    Rectangle rect = new Rectangle(100, 100, 50, 50);
             
    // Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect);
             
    // Call Inflate.
    Rectangle rect2 = Rectangle.Inflate(rect, 50, 50);
             
    // Draw the inflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Red, rect2);
}

Public Sub RectangleInflateTest(ByVal e As PaintEventArgs)

    ' Create a rectangle.
    Dim rect As New Rectangle(100, 100, 50, 50)

    ' Draw the uninflated rectangle to screen.
    e.Graphics.DrawRectangle(Pens.Black, rect)

    ' Call Inflate.
    Dim rect2 As Rectangle = Rectangle.Inflate(rect, 50, 50)

    ' Draw the inflated rectangle to screen.

注解

此方法创建 rect副本，放大副本，然后返回放大的副本。矩形沿轴向两个方向放大。例如，如果在 x 轴中放大 50 到 50 个矩形，则生成的矩形长 150 单位（原始 50，负方向为 50，加方向为 50），并保留矩形几何中心 50。
