2 types of zooms in https://www.chromium.org/developers/design-documents/blink-coordinate-spaces

We have recently upgraded and noticed a few things relating to pinch zooming on mouse pads. First we have to set 'AllowZooming = true' in options in order for pinch zooming to work again. Second when enabled in the new browser pinch zooming is changing the "Page Scale" instead of the "Page Zoom/Zoom Factor". Is there a way to change pinch zooming to change the "Page Zoom/Zoom Factor" instead of "Page Scale" like it did in previous versions (EO.Total 19.2.42)?

Also is there a way to get/set the value of "Page Scale" like we current can get/set "Page Zoom/Zoom Factor"?

Hi,

We have looked into this. The default ping zoom setting in the current version is wrong. It should be true, not false. We will fix this in our next build.

However it is not possible for us to merge the two different zoom level into one as the old version. These two types of zooms are handled by the browser engine and it would require extensive code changes to revert it back to the behavior in the old version. Beside, if we did revert it to the old version, there would be other customer who would want it to work the same as the new version because that's how current version of the Chromium engine works. As such we would prefer not to change it.

There is no public interface to get the page scale value either.

Thanks!

Thank you. Perhaps adding "AllowScaling" as an option instead. Our application appears to have no need for page scaling and we might want to keep mousepad pinch scaling turned off while leaving Page Zooming on in the future. Also since page scaling has no public interface available then we can't save and restore the setting if changed like you can in Chromium. Food for thought and thanks again.

Thank you very much for your feedback! We will look into it to see what we can do.
