Examples

Esses exemplos usam a classe GraphicsPath e Graphics para criar e manipular Figuras em uma superfície da imagem. Exemplo cria uma nova imagem (do tipo Tiff), limpa a superfície e tira caminhos com a ajuda da classe GraphicsPath. No final, o método DrawPath exposto pela classe Graphics é chamado para render os caminhos na superfície.
