PdfOptionalContentGroupVisibilityCollection

A collection of PdfOptionalContentGroupVisibility objects.

The PdfOptionalContentGroupVisibility class contains visibility settings that correspond to a layer (the PdfOptionalContentGroup object).

        processor.LoadDocument("PdfLayers.pdf");
        // Set visibility settings for each layer contained in a document.
        processor.DocumentFacade.OptionalContentVisibility.Groups[0].Visible = false;
        processor.DocumentFacade.OptionalContentVisibility.Groups[1].Visible = false;
        processor.DocumentFacade.OptionalContentVisibility.Groups[2].Visible = true;
        // Print the document.

        PdfPrinterSettings pdfPrinterSettings = new PdfPrinterSettings();
        processor.Print(pdfPrinterSettings);
    }
