Hi there,

I am looking for a library that meet my requirements.

I habe several PDF files. Each PDF has the same size, one page, CYMK color schem and contains a single part of a whole label.

Now I want to overlay 2 until XY of this PDFs to get the rights label as output.

Can I do this with you library? I tried you sample for overlay, but it does not work.

Code: Select all
//load two documents
            PdfDocument doc1 = new PdfDocument();
            doc1.LoadFromFile(secondPdf);
            PdfDocument doc2 = new PdfDocument();
            doc2.LoadFromFile(firstPdf);
            //Create page template
            PdfTemplate template = doc1.Pages[0].CreateTemplate();
            //set PDF overlay effect and set transparency mode
            foreach (PdfPageBase page in doc2.Pages)
            {
                //set transparency
                page.Canvas.SetTransparency(0.25f, 0.25f, PdfBlendMode.Overlay);
                //add the first page of doc1 to every page of doc2
                page.Canvas.DrawTemplate(template, new PointF(0, 0));
            }
            //Save pdf file.   
            doc2.SaveToFile("c:\\Overlay.pdf");
            doc1.Close();
            doc2.Close();
            //Launching the Pdf file.
            System.Diagnostics.Process.Start("c:\\Overlay.pdf");


Best Regards
Michel
