Help implementing pinch zooming

[jorgebenaventee]

Hello, I am trying to implement pinch zoom in my pdf viewer in my Angular application. I am using the new TouchManager class that handles pinching. However, when I pinch zoom, it zooms in from the upper left corner instead of the center of the gesture. Any ideas why this is might be happening?

Thank you very much!

#18179 added support a while back for specifying the center of the zoom, are you passing that new parameter properly?

I guess so as I copy-pasted the TouchManager implementation in here as an starting point

I don't know if this can help you to find the solution, but the first zoom it makes is always at 0.1 scale, no matter if you zoom in or zoom out.
