private static void AddingNewExtGState()
{
    // The path to the documents directory
    string dataDir = RunExamples.GetDataDirAsposePdfFacadesPages();

    // Graphics state parameter dictionary new name
    var gsName = "GS0";

    // Open PDF document
    using (var document = new Aspose.Pdf.Document(dataDir + "input.pdf"))
    {
        var page = doc.Pages[1];
        var dictionaryEditor = new DictionaryEditor(page.Resources);
        var states = dictionaryEditor["ExtGState"].ToCosPdfDictionary();

        var newGs = CosPdfDictionary.CreateEmptyDictionary(doc);
        var pairs = new KeyValuePair<string, ICosPdfPrimitive>[3]
        {
            new KeyValuePair<string, ICosPdfPrimitive>("CA", new CosPdfNumber(1)),
            new KeyValuePair<string, ICosPdfPrimitive>("ca", new CosPdfNumber(0.5)),
            new KeyValuePair<string, ICosPdfPrimitive>("BM", new CosPdfName("Normal"))
