The scale setting can be remember by browser, which is a nice solution.
However, sometimes I wanted to force the browser use “fit to screen” every time the user open a scheme view, is there a way to do it?
Because I usually use a very high-res map/cad drawings (e.g.6000×4000) as background image to allow user to zoom-in to see details. if it’s not “fit to screen” at the beginning, some user lost track of where they are looking at.
