Esign url in iframe - how to allow doc pan / zoom



I am evaluating your product for an esign scenario. I have run into a block and am requesting help.

I have successfully generated an envelope and received a signing URL, which displays fine in an iframe embedded in my mobile web application.

My problem is that the GroupsDocs viewer in the iframe doesn’t allow the user to zoom in on the document.

Many signers will be using mobile phones and small tablets, so this is a show stopper for me.

I am under a tight deadline to produce a proof of concept for several of our larger customers.

Please provide guidance on how I can proceed.

Hello Mike,

Thank you for using GroupDocs.Signature for Cloud service.

Yes you are right , at this moment our signature service hasn't a zoom widget, as Viewer and Annotation services. But you can try to zoom programmatically your iframe via JavaScript.

For example you can try to use a viewport meta tag to automatically zoom the contents of the HTML page to fit into a web view :

Or you can check this article for how to zoom iframe content only without using a frame set.

If you will have more questions please feel free to contact us.
