Problems adding text to a existing PDF file

Hii everyone:

I have other problem with my pdfs. I´m adding a Watermark in PDF like this:

 for (int i = 1; i <= paginas; i++)
 {
      try
    {
                  QP.SelectPage(i);

                   int capa1=QP.NewLayer();
                    QP.SetTextSize(20);
                    QP.SetTextColor(255, 0, 0);
                    QP.SetTransparency(50);
                    QP.DrawRotatedText(80,250,45,"Distribución Limitada");
                     int OC1 = QP.NewOptionalContentGroup("Conf");
                     QP.SetLayerOptional(OC1);
                     QP.MoveLayer(descriptor, 1);
                     QP.SetOptionalContentGroupVisible(OC1, 0);
                      QP.SetOptionalContentGroupPrintable(OC1, 1);
    }

After this treatment, I have my pdfs with watermark but, in some pdf file the text is correct and in ohters files the text is flipped, as a mirror of the original text.

For Example:


Image with the text CORRECT:




Image with the text INCORRECT:




I dont now why the instruction "DrawRotatedText" modifiy this text in some pdf files. I Have done proofs changing position text, angle of rotation.. and nothing!! the image is not correct!!.

Somebody knows a solution?

Thanks!!!!

thanks for the fast reply. I put the instruction before DrawingText, but only change the position of the text but, it still appear wrong...

in my pdf-content?? there are only words and searching in that document, the string or the word "rotate" doesnt exist.

You say that i have to read all the pdf using a stream (for example in VIsual Studio) and find the string rotate?? If searching in that document, I dont found the word it is not necessary to read the document arround a stream, does not?

I dont understand....

the word "Rotated" or "Rotate" or any possible similar word does not exist in the document.... whats happened now??

Thanks!
