Hi everyone!

Im using the library for add text to a existing pdf file, using this code:

QuickPDFAX0723.PDFLibrary QP = new QuickPDFAX0723.PDFLibrary();
int result = QP.UnlockKey("mykey");
int descriptor = QP.LoadFromFile(fich);
if (descriptor == 0)
{
       MessageBox.Show("Error","error");
 }
int paginas=QP.PageCount();
                    for (int i = 1; i <= paginas; i++)
                    {
                        try
                        {

                            QP.SelectPage(i);
                            QP.NewLayer();
                            QP.AddTrueTypeFont("Arial", 1);
                            QP.SetTextSize(60);
                            QP.SetTransparency(50);
                            QP.DrawRotatedText(155, 600, 315, "CONFIDENCIAL");
                            int OC1 = QP.NewOptionalContentGroup("Conf");
                            QP.SetLayerOptional(OC1);

                            QP.CompressContent();
                            QP.CompressImages(1);
                            QP.CompressFonts(1);
                            QP.CompressPage();

                            QP.NewLayer();
                            QP.AddTrueTypeFont("Arial", 1);
                            QP.SetTextSize(20);
                            QP.SetTransparency(50);
                            QP.DrawText(100, 750, usuario + " " + System.DateTime.Now);
                            int OC2 = QP.NewOptionalContentGroup("Nombre");
                            QP.SetLayerOptional(OC2);

                            QP.MoveLayer(descriptor, 1);

                            QP.CompressContent();
                            QP.CompressImages(1);
                            QP.CompressFonts(1);
                            QP.CompressPage();

                            QP.SetOptionalContentGroupVisible(OC1, 0);
                            QP.SetOptionalContentGroupPrintable(OC1, 1);
                            QP.SetOptionalContentGroupVisible(OC2, 0);
                            QP.SetOptionalContentGroupPrintable(OC2, 1);  
                        }

Im trying to draw "Confidential" and the date and user of the document as a Watermark in all pages of pdf file. 
So, if my file size before this treatment is aprox 900 kb, after is aprox 24,5 MB!!!! I think this is impossible because drawrotatetext online writes text...

I Like to solve this problem, if there are solution, because the disk space is important to me about this pdf file because its not only one: aprox i have to apply this treatment to 500 pdf files.

thanksss everyone!!!

PD: My english is horrible because i´m from spain and i´m not speak much!!!

	A quick look: A lot of the stuff in your per page loop is only needed once per PDF. Some time reading the documentation on what each function does would help a lot as well. // Once per PDF before per page loop QP.CompressImages(1); QP.CompressFonts(1); QP.AddTrueTypeFont("Arial", 1); // Once per PDF after after the per page loop completes // skip CompressPage as it just does the same only for a single page QP.CompressContent(); Edited by BEvans - 29 Dec 10 at 1:03AM
