Parâmetros

Exemplos

Para obter exemplos de código, consulte os métodos e Complement(GraphicsPath) os RectangleF.Intersect(RectangleF) métodos.

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

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

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

Public Sub Intersect (rect As Rectangle)

Parâmetros

Exemplos

Para obter um exemplo de código, consulte o Intersect(RectangleF) método.

public:
 void Intersect(System::Drawing::RectangleF rect);

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

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

Public Sub Intersect (rect As RectangleF)

Parâmetros

Exemplos

O exemplo de código a seguir foi projetado para uso com Windows Forms e requer PaintEventArgse, que é um parâmetro do manipulador de eventos Paint. O código executa as seguintes ações:

• Cria o primeiro retângulo e o desenha para a tela em preto.

• Cria o segundo retângulo e o desenha para a tela em vermelho.

• Cria uma região do primeiro retângulo.

• Obtém a área de interseção para a região quando combinada com o segundo retângulo.

• Preenche a área de interseção com azul e a desenha para a tela.

Observe que apenas a área sobreposta para a região e o retângulo é azul.
