Transfert Clipping Paths pendant l’exportation de TIFF à image PSD.

using (var image = Image.Load("Sample.tif"))
                                                                        {

                                                                        }

L’exemple ci-dessous montre comment créer Clipping Path dans l’image TIFF. Pour ce faire, vous devez créer une instance de la classe Résource. Le code suivant démontre la façon dont vous pouvez créer un chemin vide dans cet image.

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