Hi @timmywil
Shall We Expect A Update Which Resolve This Problem Many of Us Experiencing?

I found the pinch-to-zoom was not working in Chrome running on Android devices. (Though I did not test Chrome on other devices). This pull request seems to fix it.

@timmywil We know you are busy but please resolve this issue with pinch & zoom on touch enabled devices.

[DKastani]

The issue lies in the zoom function (lines 692 - 769). The scaling matrix (m) is initialized always with the default matrix [1 0 0 , 1 0 0] so it always zooms to 1.

For a quick fix I replaced the whole function with the previous version and got zooming and panning working in mobiles once again.

[PrinceDhankhar]

Can you provide that working code.

[oliversierrab]

Having a similar issue but when pinching to Zoom Out after zooming in with a separated CTA. It pans instead on zoom out.

@DKastani can you share the working code you fixed ? Thanks

see: https://github.com/Woela/jquery.panzoom

I reverted the commit that breaks zooming, and added a fix for double events (touch/pointer) on chrome.

I also requested pull requests for the issues (including this one), but that may take some time.

@maartendemandt THANK YOU
This fixed multiple issues for me, including pinch on iOS

In iPad (ios devices) Dragging and pinch to zoom in and zoom out is not working.
In mobile devices (android devices) dragging is working but pinch to zoom in and zoom out is not working.
Even I tried what you have updated also, still not working...
