Rectangle Editor

Rectangle Drawing service for creating and editing Rectangles.

Usage:

You must provide RectanglesEditorService yourself:

@Component({
  selector: 'my-map',
  templateUrl: './my-map.component.html',
  providers: [RectanglesEditorService],
})
export class MyMapComponent {}

<ac-map id="my-map"></ac-map>

RectanglesEditorService works together with <rectangles-editor> component. Therefor you need to create <rectangles-editor>for each RectanglesEditorService of course somewhere under <ac-map>

<ac-map id="my-map">
   <rectangles-editor></rectangles-editor>
</ac-map>
​

Thats it! just Inject the service and use the create() and edit() methods:

@Component({...})
export class MyMapComponent {
    editing$: RectangleEditorObserver;
    
    constructor(private rectangleEditor: RectanglesEditorService) {}
    
    startDraw() {
         this.editing$ = this.rectangleEditor.create();
    });
    }
}

Api

• create(options?: RectangleEditOptions, priority?: number)

Start a creating a Rectangle over the map, Returns: RectangleEditorObservable

 // Start creating 
 const editing$ = rectangleEditor.create();
 this.editing$.subscribe(editResult => {
 			console.log(editResult.positions);
 	});

• edit(positions: Cartesian3[], options: RectangleEditOptions, priority?: number)

Start editing a Rectangle over the map from a given positions, minimum 2 positions. Returns: RectangleEditorObservable

const editing$ = this.rectangleEditor.edit(initialPositions);

• The editor is fully customisable with RectangleEditOptions :

  • addPointEvent - Set Cesium event for adding last point, default: LEFT_CLICK

  • addPointModifier - Set Cesium event modifier for adding point, default: none

  • dragPointModifier - Set Cesium event modifier for draging a point, default: LEFT_DRAG

    • In edit mode only

  • dragPointModifier - Set Cesium event modifier for removing a point, default: none

    • In edit mode only

  • rectangleProps - Rectangle customisation properties

  • allowDrag - allow shape drag, default: false

    • In edit mode only

  • pickConfiguration - configure pick behaviour with: pick height and width and drill pick limit

  • setLabelsRenderFn - receives a callback that is called every time the shape is redrawn (except when the shape is being dragged). The callback is called with the last shape state and with an array of the current labels.

    • The callback should return LabelProps[]
