Dapatkan Preferensi Penampil File PDF

Dapatkan Preferensi Penampil dari File PDF yang Ada

Kelas ViewerPreference mewakili mode tampilan dari file PDF; misalnya, menempatkan jendela dokumen di tengah layar, menyembunyikan bilah menu aplikasi penampil, dll.

Untuk membaca pengaturan, kami menggunakan Kelas GetViewerPreference. Metode ini mengembalikan variabel di mana semua pengaturan disimpan.

.NET Core 3.1

private static void GetViewerPreference()
{
    // The path to the documents directory
    var dataDir = RunExamples.GetDataDir_AsposePdf_WorkingDocuments();

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "SetViewerPreference.pdf"))
    {
        // Instantiate PdfContentEditor object
        var editor = new Aspose.Pdf.Facades.PdfContentEditor(document);

        // Get Viewer Preferences
        var preferences = editor.GetViewerPreference();

        if ((preferences & Aspose.Pdf.Facades.ViewerPreference.CenterWindow) != 0)
        {
            Console.WriteLine("CenterWindow");
        }

        if ((preferences & Aspose.Pdf.Facades.ViewerPreference.HideMenubar) != 0)
        {
            Console.WriteLine("Menu bar hided");
        }

        if ((preferences & Aspose.Pdf.Facades.ViewerPreference.PageModeFullScreen) != 0)
        {
            Console.WriteLine("Page Mode Full Screen");
        }
    }
