CornersGeoreference is used to set the geographic location of the image or element referenced in the MediaLayer using corner points of a bounding box.
// create a canvas image element by setting its corner points of the bounding box
const canvasElement = new ImageElement({
image: canvas,
georeference: new CornersGeoreference({
bottomRight: new Point({
x: -121.369,
y: 45.061,
spatialReference: {
wkid: 4326
}
}),
bottomLeft: new Point({
x: -122.363,
y: 45.061,
spatialReference: {
wkid: 4326
}
}),
topRight: new Point({
x: -121.369,
y: 45.678,
spatialReference: {
wkid: 4326

Inherited from Accessor
Since: ArcGIS Maps SDK for JavaScript 4.25Accessor since 4.0, addHandles added at 4.25. -
Adds one or more handles which are to be tied to the lifecycle of the object. The handles will be removed when the object is destroyed.
// Manually manage handles const handle = reactiveUtils.when( () => !view.updating, () => { wkidSelect.disabled = false; }, { once: true } ); this.addHandles(handle); // Destroy the object this.destroy();ParametershandleOrHandles WatchHandle|WatchHandle[]Handles marked for removal once the object is destroyed.
groupKey *optionalKey identifying the group to which the handles should be added. All the handles in the group can later be removed with Accessor.removeHandles(). If no key is provided the handles are added to a default group.
