    pdf.propertiesSet("Sample document title", "Sample subject", "keyword1, keyword 2, keyword3", "Document Author Name", "Document Creator Name");
 
    // add a page with portrait orientation
    pdf.pageSetOrientation(BytescoutPDF.PORTRAIT); // BytescoutPDF.PORTRAIT = portrait, BytescoutPDF.LANDSCAPE = landscape
    pdf.pageAdd();
 
    pdf.textAdd(50, 50, 'Portrait page orientation', 0);
 
    // add a page with landscape orientation
    pdf.pageSetOrientation(BytescoutPDF.LANDSCAPE);
    pdf.pageAdd();
