Rectangle.Inflate 方法

定义

Rectangle 结构放大指定量。

重载

Inflate(Size)

将此 Rectangle 放大指定量。

Inflate(Int32, Int32)

将此 Rectangle 放大指定量。

Inflate(Rectangle, Int32, Int32)

创建并返回指定 Rectangle 结构的放大副本。 该副本被放大指定的量。 不修改原始 Rectangle 结构。

Inflate(Size)

Rectangle.cs

将此 Rectangle 放大指定量。

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

此矩形的放大量。

示例

以下示例旨在与 Windows 窗体 一起使用,它需要 PaintEventArgse,这是事件处理程序的参数Paint。 该代码创建 ,并在两个 Rectangle 轴上将其放大 50 个单位。 矩形绘制到屏幕之前,膨胀 (黑色) 和通货膨胀 (红色) 。

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,而不是它的副本。 矩形沿轴向两个方向放大。 例如,如果一个 50 x 50 矩形在 x 轴中放大 50,则生成的矩形长 (原始 50 单位,50 个单位在负方向,加号方向的 50 个单位) 保持矩形的几何中心。

适用于

Inflate(Int32, Int32)

Source:
Rectangle.cs
Source:
Rectangle.cs
Source:
Rectangle.cs

将此 Rectangle 放大指定量。

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

Rectangle 的水平放大量。

height
Int32

Rectangle 的垂直放大量。

示例

以下示例创建一个 Rectangle 结构,并在 x 轴方向上将其放大 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

此方法放大此矩形,而不是它的副本。 矩形沿轴向两个方向放大。 例如,如果一个 50 x 50 矩形在 x 轴中放大 50,则生成的矩形长 (原始 50 单位,50 个单位在负方向,加号方向的 50 个单位) 保持矩形的几何中心。

x如果 或 y 为负值,则Rectangle结构在相应的方向上放气。

适用于

Inflate(Rectangle, Int32, Int32)

Source:
Rectangle.cs
Source:
Rectangle.cs
Source:

创建并返回指定 Rectangle 结构的放大副本。 该副本被放大指定的量。 不修改原始 Rectangle 结构。

public:
 static System::Drawing::Rectangle Inflate(System::Drawing::Rectangle rect, int x, int y);
public static System.Drawing.Rectangle Inflate (System.Drawing.Rectangle rect, int x, int y);
static member Inflate : System.Drawing.Rectangle * int * int -> System.Drawing.Rectangle
Public Shared Function Inflate (rect As Rectangle, x As Integer, y As Integer) As Rectangle

参数

rect
Rectangle

要从其开始操作的 Rectangle。 不修改此矩形。

x
Int32

Rectangle 的水平放大量。

y
Int32

Rectangle 的垂直放大量。

返回

放大的 Rectangle

示例

以下示例旨在与 Windows 窗体 一起使用,它需要 PaintEventArgse,这是事件处理程序的参数Paint。 该代码创建 ,并在两个 Rectangle 轴上将其放大 50 个单位。 请注意,生成的矩形 (红色) 两个轴均为 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.
    e.Graphics.DrawRectangle(Pens.Red, rect2)
End Sub

注解

此方法创建 rect的副本,放大副本,然后返回放大后的副本。 矩形沿轴向两个方向放大。 例如,如果一个 50 x 50 矩形在 x 轴中放大 50,则生成的矩形长 (原始 50 单位,50 个单位在负方向,加号方向的 50 个单位) 保持矩形的几何中心。
