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();
