Is there a MapView fullExtent ?

RomanKönig — Wed, 29 May 2019 14:42:22 GMT

I couldn't find anything about this in the documentation - is there no fullExtent property or equivalent on a MapView?

There are fullExtent properties on various layer types, but not on a MapView.

What we want to be able to, is limit the navigation availabilities of the user to a certain extent of interest, independent on the fullExtent defined on layer level. On a WebScene of local type there is also a clippingArea which would be nice on MapView level as well.

Is there anything like that i don't see?

Thanks in advance

This is what we have done to limit panning outside of a certain extent. It definitely seems like a work around. But it works for us.

const maxExtent = new Extent({
                xmax: -12014182,
                xmin: -12867508,
                ymax: 4497591,
                ymin: 3571786,
                spatialReference: 102100
});
view.watch('extent', function(extent) {
                let currentCenter = extent.center;
                if (!maxExtent.contains(currentCenter)) {
                    let newCenter = extent.center;
                    if (currentCenter.x < maxExtent.xmin) {
                        newCenter.x = maxExtent.xmin;
                    }
                    if (currentCenter.x > maxExtent.xmax) {
                        newCenter.x = maxExtent.xmax;
                    }
                    if (currentCenter.y < maxExtent.ymin) {
                        newCenter.y = maxExtent.ymin;
                    }
                    if (currentCenter.y > maxExtent.ymax) {
                        newCenter.y = maxExtent.ymax;
                    }

                    let newExtent =view.extent.clone();
                    newExtent.centerAt(newCenter);
                   view.extent = newExtent;
}
});

Thanks for your reply. We've also implemented this workaround, but i thought there had to be something we might have missed. Setting a fullExtent or clipping on mapview level would be great.
