public ImageSaveOptions Clone()

Exempel

Visar hur man väljer en bit-per-pixel-hastighet med vilken ett dokument ska renderas till en bild.

Document doc = new Document();
            DocumentBuilder builder = new DocumentBuilder(doc);

            builder.ParagraphFormat.Style = doc.Styles["Heading 1"];
            builder.Writeln("Hello world!");
            builder.InsertImage(ImageDir + "Logo.jpg");

            Assert.That(20000, Is.LessThan(new FileInfo(ImageDir + "Logo.jpg").Length));

            // När vi sparar dokumentet som en bild kan vi skicka ett SaveOptions-objekt till
            // välj ett pixelformat för bilden som sparas.
            // Olika bit per pixelhastigheter kommer att påverka kvaliteten och filstorleken på den genererade bilden.
            ImageSaveOptions imageSaveOptions = new ImageSaveOptions(SaveFormat.Png);
            imageSaveOptions.PixelFormat = imagePixelFormat;

            // Vi kan klona ImageSaveOptions-instanser.
            Assert.AreNotEqual(imageSaveOptions, imageSaveOptions.Clone());

            doc.Save(ArtifactsDir + "ImageSaveOptions.PixelFormat.png", imageSaveOptions);
