How do I create bookmarks (in the javascript code) using point and scale (rather than extent)?

WWUMap

Hi,

I'm using the Bookmarks widget, preloading bookmarks in the JavaScript code.
It works fine using type: extent:

new Bookmark({
name: "Test1",
viewpoint: {
targetGeometry: {
type: "extent",
xmin: -122.486,
ymin: 48.738,
xmax: -122.484,
ymax: 48.739
} } }),

 

But the scale isn't working for type: point:

new Bookmark({
name: "Test2",
viewpoint: {
targetGeometry: {
type: "point", 
longitude: -122.488,
latitude: 48.73,
scale: ???
} } }),
    

How do I specify / use the scale parameter?

thanks,

Hi Stefan,

The scale property needs to be set on the Viewpoint, not on the target geometry. See the example below:

const bookmark = new Bookmark({
    name: "Test",
    viewpoint: {
        scale: 1600,
        targetGeometry: {
            type: "point",
            longitude: -122.488,
            latitude: 48.73
        }
    }
});

 The following sample shows this same code in action on lines 55-66: https://codepen.io/laurenb14/pen/JjrEYmO?editors=1000

Hope that helps!
