Zooming

The zooming feature is used to zoom in and out of Maps to show in-depth information. It is controlled by the zoomFactor property of the zoomSettings. The zoomFactor is increased or decrease dynamically based on zoom in and out interaction.

Enable zooming

Zooming of Maps is enabled by setting the enable property of zoomSettings to true.

Enable panning

To enable the panning feature, set the enablePanning property of zoomSettings to true.

import { world_map } from './world-map';

Various type of zooming

Zooming can be performed in following types:

Zooming toolbar

The following options are available in toolbar.

  1. Zoom - Provides rectangular zoom support.
  2. ZoomIn - Zooms in the Maps.
  3. ZoomOut - Zooms out the Maps.
  4. Pan - Switches to panning if rectangular zoom is activated.
  5. Reset - Restores the Maps to the default view.
import { Component, OnInit } from '@angular/core';
import { Maps, Zoom } from '@syncfusion/ej2-angular-maps';
import { world_map } from 'world-map.ts';
Maps.Inject(Zoom);
@Component({
    selector: 'app-container',
    template:
    `<ejs-maps id='rn-container' [zoomSettings] = 'zoomSettings'>
     <e-layers>
    <e-layer [shapeData] = 'shapeData'></e-layer>
    </e-layers>
    </ejs-maps>`
})
export class AppComponent implements OnInit {
    public zoomSettings: object;
    public shapeData: object;
    ngOnInit(): void {
        this.zoomSettings = {
            enable: true,
            toolbarSettings: {
               buttonSettings: {
                  toolbarItems: ['Zoom', 'ZoomIn', 'ZoomOut', 'Pan', 'Reset'],
               }
            }
        };
        this.shapeData = world_map;
    }
}

Pinch zooming

To enable or disable the pinch zooming, use the pinchZooming property in zoomSettings.

import { Component, OnInit } from '@angular/core';
import { Maps, Zoom } from '@syncfusion/ej2-angular-maps';

    <e-layer [shapeData] = 'shapeData'></e-layer>
    </e-layers>
    </ejs-maps>`
})
export class AppComponent implements OnInit {

            enable: true,
            pinchZooming:true
        };
        this.shapeData = world_map;
    }
}

Single-click zooming

To enable or disable the single-click zooming, use the zoomOnClick property in zoomSettings.

import { Component, OnInit } from '@angular/core';
import { Maps, Zoom } from '@syncfusion/ej2-angular-maps';
import { world_map } from 'world-map.ts';
Maps.Inject(Zoom);
@Component({

            doubleClickZoom:true
        };
        this.shapeData = world_map;
    }
}

Mouse wheel zooming

To enable or disable mouse wheel zooming, use the mouseWheelZoom property in zoomSettings.

    ngOnInit(): void {
        this.zoomSettings = {
            enable: true,
            mouseWheelZoom:true
        };
        this.shapeData = world_map;
    }
}

Selection zooming

To enable or disable selection zooming, use the enableSelectionZooming property in zoomSettings. The enablePanning property must be set to false to enable the selection zooming in Maps.

import { Component, OnInit } from '@angular/core';
import { Maps, Zoom } from '@syncfusion/ej2-angular-maps';
import { world_map } from 'world-map.ts';
Maps.Inject(Zoom);
@Component({
    selector: 'app-container',
    template:
    `<ejs-maps id='rn-container' [zoomSettings] = 'zoomSettings'>

        this.shapeData = world_map;
    }
}

    ngOnInit(): void {
        this.zoomSettings = {
        enable: true,
    };
        this.shapeData = world_map;
    }
}

Enable selection for bubbles

To enable the selection for bubbles in Maps, set the selectionSettings in bubbleSettings and set the enable property of selectionSettings as true.

To use the bubble feature, the Bubble module must be injected.

Enable selection for polygons

When the enable property of selectionSettings is set to true, the polygon shapes can be selected via user interaction. The following properties are available in selectionSettings to customize the polygon shape when it is selected.

  • enableMultiSelect - It is used to enable multiple selection of polygon shapes.
  • fill - It is used to change the color of the selected polygon shape.
  • opacity - It is used to change the opacity of the selected polygon shape.
  • border - This property is used to change the color, width, and opacity of the border of the selected polygon shape.

To use the polygon feature, the Polygon module must be injected, as described in this link.

The following example shows how to select the polygon shape in the geometry map.

import { Component, ViewEncapsulation, OnInit } from '@angular/core';
import { world_map } from './world-map';

Public method for the shape selection

The shapeSelection method can be used to select each shape in the Maps.
LayerIndex, propertyName, country name, and selected value as a boolean state(true / false) are the input parameters for this method.

Initial shape selection

The shape is initially selected using the initialShapeSelection, and the values are mapped to the shapePath and shapeValue.

initialShapeSelection is an Array property.

Highlight

Each shape in the Maps can be highlighted during mouse hover on the Maps elements such as shapes, bubbles, markers and legends. Highlight is enabled by setting the enable property of highlightSettings to true.

The following properties are available to customize the highlight of Maps elements such as shapes, bubbles, markers and legends.

  • border - To customize the color, width and opacity of the border of which element is highlighted in Maps.
  • fill - Applies the color for the element that is highlighted.
  • opacity - To customize the transparency for the element that is highlighted.

Hovering on the specific legend, the shapes which are bounded to the selected legend is also highlighted and vice versa.

Enable highlight for bubbles

To enable the highlight for bubbles in Maps, set the highlightSettings in bubbleSettings and set the enable property of highlightSettings as true.

To use the bubble feature, the Bubble module must be injected.

Enable highlight for polygons

The polygon shapes can be highlighted via user interaction if the enable property of highlightSettings is set to true. The following properties are available in highlightSettings to customize the polygon shape when it is highlighted.

  • fill - It is used to change the color of the highlighted polygon shape.
  • opacity - It is used to change the opacity of the highlighted polygon shape.
  • border - This property is used to change the color, width, and opacity of the border of the highlighted polygon shape.

To use the polygon feature, the Polygon module must be injected, as described in this link.

The following example shows how to highlight a polygon shape on a geometry map.

import { Component, ViewEncapsulation, OnInit } from '@angular/core';

Tooltip

On mouse over or touch end event, the tooltip is used to get more information about the layer, bubble, or marker. To enable tooltip in Maps, the Tooltip module must be injected into Maps using Maps.Inject(Tooltip) method. It can be enabled separately for layer or bubble or marker by using the visible property of tooltipSettings as true. The valuePath property in the tooltip takes the field name that presents in data source and displays that value as tooltip text. The tooltipDisplayMode property is used to change the display mode of the tooltip in Maps. Following display modes of tooltip are available in the Maps component. By default, tooltipDisplayMode is set to MouseMove.

  • MouseMove
  • Click
  • DoubleClick
