JavaScript ArcGIS: Update scene clipping area after creation

Serbian — Tue, 16 Aug 2022 12:03:39 GMT

I want to update (increase / decrease) scene clipping area after I create it. My goal is to give the user ability to adjust the clipping area. I am using scene view, if that's relevent.

I've managed to update the clipping area of the map using:

const extent = view.clippingArea.clone();
view.clippingArea = extent.expand(0.5);

However when I try to set it to a specific range it does not want work:

let extent = view.clippingArea.clone();
extent.extent.xmax = 1849093
extent.extent.xmin = 1488933
extent.extent.ymax = 5921967
extent.extent.ymin = 5688179

view.clippingArea = extent

How can I set clipping area to specific range.

Hi @Serbian!

Looks like you use one level of `extents` too many in your code. Try instead:

let extent = view.clippingArea.clone(); extent.xmax = 1849093; extent.xmin = 1488933; extent.ymax = 5921967; extent.ymin = 5688179; view.clippingArea = extent;

Alternatively, you can also substitute the whole clippingArea with a new Extent at once (without cloning):

view.clippingArea = { // autocasts as new Extent() xmax: 1849093, xmin: 1488933, ymax: 5921967, ymin: 5688179, spatialReference: { // autocasts as new SpatialReference() wkid: 3857 // Make sure this is the wkid of the spatial reference your view uses! } };

Here's a sample app which switches between 3 different clipping extents: https://codepen.io/gsoosalu/pen/MWVPREJ
