How do I change the initial magnification level?

[Crix]

Hello there,

I was just wondering whether and - if yes - how it is possible to set the Initial magnification level of a document to "Default" using Spire.PDF, as I have to format hundreds of PDF documents. I managed to set the other properties like PageLayout etc., however i did not find any documentation about magnification so far. Sorry to bother you in case I missed it.

Thanks in advance,
Crix

Hi Crix,

Thanks for your posting.
Please try the following solution.

Code: Select all

PdfDocument pdf = new PdfDocument();
            pdf.LoadFromFile("..\\..\\test.pdf");
            foreach (PdfPageBase page in pdf.Pages)
            {
                PdfDestination dest = new PdfDestination(page);
                dest.Location = new PointF(-40f, -40f);
                dest.Zoom = 0f;
                PdfGoToAction gotoAction = new PdfGoToAction(dest);
                pdf.AfterOpenAction = gotoAction;
            }
            pdf.SaveToFile("result.pdf");
