Transferir Paths Clipping durante la exportación de TIFF a la imagen PSD.

using (var image = Image.Load("Sample.tif"))
                                                                        {
                                                                            image.Save("SampleWithPaths.psd", new PsdOptions());
                                                                        }

El siguiente ejemplo muestra cómo crear Clipping Path en la imagen TIFF. Para hacerlo, necesita crear una instancia de la clase PathResource. El código siguiente muestra cómo puede crear un camino vacío en la imagen TIFF.

var options = new TiffOptions(TiffExpectedFormat.Default);
                                                                                                                                                                                                                                                   var frame = new TiffFrame(options, 800, 600);
