PDF Viewer: Add pinch to zoom

[rlburg]

Please add pinch to zoom in the integrated PDF Viewer. Having to use the controls is not a good user experience on a mobile device, plus it typically crashes the app if you hit the + symbol too many times quickly.

A very important function that must be added. +- controls are a thing of past

I agree, please add the pinch to zoom.

Pinch to zoom seems to exist now on iOS. ...But it crashes the app and there's no way to disable it.

The pinch to zoom is still crashing on some iOS devices, it doesn't matter if zooming in or out, the app just restarts itself.

Even when using the controls to zoom in, is anyone else having resolution issues?  If i view the pdf and zoom in in the bluebeam app, it is crystal clear, but the resolution when you zoom in the powerapp is really poor to the point that the text is illegible.  (specific application - 36x48 construction documents).

Are there any news regarding this request? We are experiencing issues with the standard application zoom. The application turns black and is restarted when using touch zoom.

Hi there,

We've seen cases where on mobile devices the PDF viewer crashes when trying to pinch zoom.  We're actively looking into this issue to see if there are ways to make it more reliable. 

Out of curiosity, does it happen with every PDF of only large PDFs? 

[lukasnaslund]

Hi, 

Thank you for the information! 

The application crashes more often when the PDF is larger, although I have seen it on smaller PDFs as well.  

Best regards,

I can also confim it happens in an application for one of our customers.
