ZoomMode

[wcruzcc@gmail.com]

I want the PDF to scale down or up to whatever the control size is. I try modifying "ZoomMode" with no luck. Is this the correct place to do this?

Hello,

Thanks for your inquiry. You can try to use the following method.

Code: Select all

 //
        // Summary:
        //     Zoom PDF document
        //
        // Parameters:
        //   percentage:
        //     Zoom percentage
        public void ZoomTo(int percentage);


Sincerely,

It doesn't matter what I put as a value, the PDF does not change.

Code: Select all

 private void button1_Click(object sender, EventArgs e)
        {
            pdfDocumentViewer1.ZoomTo(25);

            pdfDocumentViewer1.LoadFromFile("C:\\Document.pdf");
        }

I though that this property needed to be set before loading the document. I moved it after the loadfromfile and now it scales as it should. If only there was a way to have it automatically scale to the pdfdocumentviewer window.

Hello,

Thanks for your response. You can set the ZoomMode as FitWidth to automatically scale to the pdfdocumentviewer window.

Code: Select all

pdfDocumentViewer.ZoomTo(Spire.PdfViewer.Forms.ZoomMode.FitWidth);
