Hi Jonathan,
Further to your feedback and feature request at the OME meeting last week, I have returned to the example we were working on before and opened a new PR:
https://github.com/openmicroscopy/omero-webtest/pull/24The bugs we fixed previously are still working, and I added extra example code to sync the zooming and panning of the 2 viewers. This code is a little cumbersome since it needed to use functionality that is not provided by the existing viewer code. (NB: this also doesn't work for Big (tiled) images since they use a different viewer).
Have a look under the new files code at the above PR (see JavaScript code under "// Link zooming of both viewports") and see if this works for you.
You can leave feedback here or on the PR itself.
Regards,
Will.
