Exemplos

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

• Cria um retângulo e o desenha para a tela em preto

• Cria um segundo retângulo que se cruza com o primeiro e o desenha para a tela em vermelho.

• Cria uma região usando o primeiro retângulo e cria uma segunda região usando o segundo retângulo.

• Obtém o complemento dessa primeira região quando combinado com a segunda região.

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

Observe que a área da segunda região que não se cruza com a primeira região é azul colorida.
