Pdf.js: customizing when it comes to zooming a specific pdf file in linux

[SehyunPark]

When browsing the pdf file using pdf.js viewer, I found out that when it comes to zooming,
there are the selected options (e.g 50%, 75%, 100%, etc).
how can I zoom in the file while using customized zooming version? (e,g 53% 20%)

There are no personally customized zooming options
Using the customized option , it would be much helpful for the ones who want to see the pdf file based on what they want to see the slide with the size they need

If you need a specific zoom level, the easiest solution is to append e.g. #zoom=20 (or whatever value you need) to the URL; please see https://github.com/mozilla/pdf.js/wiki/Viewer-options for additional details.

Thanks for the reply, and after entering (e.g 17%) in URL, it works.

and after giving several tries, found out the file is zoomed with the %(_up to second decimal place_)
(e.g #zoom = 80.50923 -> 80.51%; as shown above)
