Please close this thread. I have managed to use the Aspose.Pdf.TextStamp object to achive my objectives.

Hi Hadi,

Thanks for contacting support.

I am glad to hear that your problem is resolved. However I have gone through the code snippet that you have shared and have observed that the problem was occurring because in method DrawOMROnPDF(…) you wanted to load PDF file in Aspose.Pdf.Generator.Pdf object. Please note that Aspose.Pdf.Generator namespace only supports the feature to create PDF document from scratch.

Besides this, you may also accomplish your requirement using CreateLine method of PdfContentEditor class present under Aspose.Pdf.Facades namespace.


PdfContentEditor editor = new


editor.CreateLine(new System.Drawing.Rectangle(0, 0, 100, 100), "Welcome to Aspose", 0, 0, 100, 100,

1, 1, System.Drawing.Color.Red, "D", new int[] { 2, 3 }, new string[] { "OpenArrow", "ClosedArrow" });


In case of any further query, please feel free to contact.

Hi Nayyer,

Thanks very much for your assistance. At the end, i choose the AddStamp() method which achieves my objectives properly.

The details of the code snippet can be found in the following thread :
