Syncfusion PDF viewer default zoom not working

[Anand Raj]

Hi Syncfusion team,

I am using Syncfusion Pdf viewer in my xamarin.forms UWP app. The pdf zoompercentage ​not working for me.

I am using syncfusion pdfviewer version : 18.4.0.41

What I am trying to achieve is , make the pdf width fit to screen defaultly. Currently it is loading as small and we need to manually zoom in for better readability.  I tried to set the  ViewMode="FitWidth" and Zoomzpercentage ="100". But no luck.

My xaml

   <StackLayout

                            HorizontalOptions="FillAndExpand"

                            VerticalOptions="FillAndExpand">

                            <syncfusion:SfPdfViewer

                                HorizontalOptions="FillAndExpand"

                                InputFileStream="{Binding FileInBase64, Converter={StaticResource base64ToStreamConverter}}"

                                IsPasswordViewEnabled="False"

                                PageViewMode="PageByPage"

                                ShowPageNumber="True"

                                ZoomPercentage="100"

                                ViewMode="FitWidth"

                                Toolbar="{StaticResource ToolbarSettings}"

                                VerticalOptions="FillAndExpand">      

                            </syncfusion:SfPdfViewer>

                        </StackLayout>

Any help for solving this issue is appriciated,.

Reagards,

Hi Anand,   

    

We have confirmed that the issue “Default zoom not working properly in viewer” is a defect and logged a defect report for this issue. The patch for this issue will be delivered on  August 12, 2021.   

   

Please find the feedback link below,

NOTE: As current behavior, navigating pdf pages in single page view mode will fit to the view port regardless of the zoom applied to the previous pages. So even the above issue fixed only the first or default page get given default zoom percentage value. Currently we do not have support to retain pdf page zoom while navigating PDF pages in single page view mode.  

Please find the feedback link below to know more about the “Support to retain zoom while navigating PDF pages in single page view mode” feature:
