Hi Karsten!

Changing directly inside a created pdf won't succeed with QP.

For my opinion you have to extract all content... then resize

the images and then reassamble the pages.

If you have luck the new result looks similar to the old one ;-)

Sorry.

Cheers, Ingo

Hi,

I must reduce the filesize of my PDFs and save as new one.
How can I change the imageresolution of alle images to 72 dpi wit QuickPDFLibrary?

This code don't do this

private static void resizePDF(string source, string target)
        {
            PDFLibrary QP = new PDFLibrary(@"QuickPDFDLL0816.dll");
            string licenseKey = "...licensekey...";
            QP.UnlockKey(licenseKey);

            int FileHandle = QP.LoadFromFile(source, "");
            int numPages = QP.PageCount();
            int numImages = QP.FindImages();
            for (int i = 1; i <= numPages; i++)
            {
                for (int j = 1; j <= numImages; j++)
                {
                    int idxImage = QP.GetImageID(i);
                    QP.SelectImage(idxImage);
                    QP.SetImageResolution(72,72,2);
                }
            }

            QP.SaveToFile(target);
        }

Regards
Karsten
