I’d like to share a trick to implement some sort of simple cluttering effect in Perspective.
As it shown in above the root container of your view should has a zoom property under style.
The value of this property can be adjust by a slider from 1(100%) to 0.6(60%). This cause every things only in this view zoom in/out.(Not whole page like browser zoom)
As we know the current user zoom level now, we can simply use it as condition of visibility of any object in the view.
You can put your zoom slider in dock view so the size of your slider size doesn’t change while you change view zoom level.
This is very useful in large overview diagram or SLD diagram that has a lot of details and can not be fit in your view at 100% zoom.
At startup script I set the zoom level to something like 0.6, so all of my objects seen in the view and user can zoom in to see additional details.
I hope in near future IA add a special container to support this like map component.
