Disable zooming on SFPdfViewer

[Thomas Sebastian Jensen]

Hi,

I'm trying to disable the zoom possibility on teh SFPdfViewer on Xamarin.Forms for Android and iOS.

I'm trying to set the ZoomPercentage, MinimumZoomPercentage and MaximumZoomPercentage all to the same value, like 100, but I'm still able to zoom via the Pinch-And-Zoom gesture.

So how can I disable the zooming via the Pinch-And-Zoom gesture, but a scrolling with one finger

Hi Thomas,

We were unable to replicate the issue “Disabling zoom is not working properly” and it is working fine for us. Could you please try the attached sample and let us know whether we have missed out anything while replicating the issue. 

  

Please find the below code snip to disable the zoom,

            pdfViewerControl.ZoomPercentage = 100;

            pdfViewerControl.MinimumZoomPercentage = 100;

            pdfViewerControl.MaximumZoomPercentage = 100;

Kindly share the following details to analyze more on this issue and assist you with the better solution   

1.Simple sample/ modify the above sample to reproduce the issue.  

2.Replication video/procedure to reproduce the issue. 

3.PDF document  

4. SfPdfViewer version

Vikram

This is very wired.

I've tried your sample and everything is working. If I use exactly the same approach within my own application it doesn't work.

Although I set ZoomPercentage, MinimumZoomPercentage and MaximumZoomPercentage to 100 I'm still able to zoom via the pinch-and-zoom gesture.

I'm using a ViewModel approach but I've also tested to load the PDF stream in the code-behind file. I've also tried to use the PDF file provided wihtin the sample, without any l So I think that I need to investigate a little bit more which causes the issue on my app.
