Rectangle.Intersect Método

Definição

Namespace:

System.Drawing

Assembly:

System.Drawing.Primitives.dll

Determina a estrutura Rectangle que representa a interseção de dois retângulos.

Sobrecargas

Intersect(Rectangle, Rectangle)	Retorna uma terceira estrutura Rectangle que representa a interseção de duas outras estruturas Rectangle. Se não houver nenhuma interseção, um Rectangle vazio será retornado.
Intersect(Rectangle)	Substitui este Rectangle com a interseção de si mesmo e o Rectangle especificado.

Intersect(Rectangle, Rectangle)

Origem:

Rectangle.cs

Retorna uma terceira estrutura Rectangle que representa a interseção de duas outras estruturas Rectangle. Se não houver nenhuma interseção, um Rectangle vazio será retornado.

public:
 static System::Drawing::Rectangle Intersect(System::Drawing::Rectangle a, System::Drawing::Rectangle b);

public static System.Drawing.Rectangle Intersect (System.Drawing.Rectangle a, System.Drawing.Rectangle b);

static member Intersect : System.Drawing.Rectangle * System.Drawing.Rectangle -> System.Drawing.Rectangle

Public Shared Function Intersect (a As Rectangle, b As Rectangle) As Rectangle

Parâmetros

a

Rectangle

Um retângulo a fazer interseção.

b

Rectangle

Um retângulo a fazer interseção.

Retornos

Rectangle

Um Rectangle que representa a interseção de a e b.

Exemplos

O exemplo de código a seguir demonstra os IntersectIsEmpty membros e IntersectsWith . Este exemplo deve ser usado com um Windows Form. Cole esse código em um formulário e chame esse método ao manipular o evento do Paint formulário, passando e como PaintEventArgs.

private:
   void StaticRectangleIntersection( PaintEventArgs^ e )
   {
      Rectangle rectangle1 = Rectangle(50,50,200,100);
      Rectangle rectangle2 = Rectangle(70,20,100,200);
      e->Graphics->DrawRectangle( Pens::Black, rectangle1 );
      e->Graphics->DrawRectangle( Pens::Red, rectangle2 );
      if ( rectangle1.IntersectsWith( rectangle2 ) )
      {
         Rectangle rectangle3 = Rectangle::Intersect( rectangle1, rectangle2 );
         if (  !rectangle3.IsEmpty )
         {
            e->Graphics->FillRectangle( Brushes::Green, rectangle3 );
         }
      }
   }

private void StaticRectangleIntersection(PaintEventArgs e)
{
    Rectangle rectangle1 = new Rectangle(50, 50, 200, 100);
    Rectangle rectangle2 = new Rectangle(70, 20, 100, 200);
    Rectangle rectangle3 = new Rectangle();

    e.Graphics.DrawRectangle(Pens.Black, rectangle1);
    e.Graphics.DrawRectangle(Pens.Red, rectangle2);

    if (rectangle1.IntersectsWith(rectangle2))
    {
        rectangle3 = Rectangle.Intersect(rectangle1, rectangle2);
        if (!rectangle3.IsEmpty)
        {
            e.Graphics.FillRectangle(Brushes.Green, rectangle3);
        }
    }
}

Private Sub StaticRectangleIntersection(ByVal e As PaintEventArgs)
    Dim rectangle1 As New Rectangle(50, 50, 200, 100)
    Dim rectangle2 As New Rectangle(70, 20, 100, 200)
    Dim rectangle3 As New Rectangle

    e.Graphics.DrawRectangle(Pens.Black, rectangle1)
    e.Graphics.DrawRectangle(Pens.Red, rectangle2)

    If (rectangle1.IntersectsWith(rectangle2)) Then
        rectangle3 = Rectangle.Intersect(rectangle1, rectangle2)
        If Not rectangle3.IsEmpty Then
            e.Graphics.FillRectangle(Brushes.Green, rectangle3)
        End If
    End If
End Sub

public void Intersect (System.Drawing.Rectangle rect);

member this.Intersect : System.Drawing.Rectangle -> unit

Public Sub Intersect (rect As Rectangle)

Parâmetros

rect

Rectangle

O Rectangle com o qual fazer a interseção.
