selectionColor - To apply the color for the zooming toolbar when clicking the zooming toolbar in Maps.
toolBarOrientation - To customize the orientation of the zooming toolbar.
toolbars - To customize the items that are to be shown in the zooming toolbar in Maps.
verticalAlignment - To customize the position type of toolbar when it is placed vertically.

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;

    this.zoomSettings = {
        enable: true,
        color: 'green',
        highlightColor: 'blue',
        selectionColor: 'orange',
        horizontalAlignment: 'Center',
        toolbars: ['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';
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,
        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({
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,
        zoomOnClick:true
    };
    this.shapeData = world_map;
}
}

Double-click zooming

To enable or disable the double-click zooming, use the doubleClickZoom 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({
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,
        doubleClickZoom:true
    };
    this.shapeData = world_map;
}
}

Mouse wheel zooming

To enable or disable mouse wheel zooming, use the mouseWheelZoom 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({
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,
        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'>
 <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,
        enableSelectionZooming: true,
        enablePanning: false
    };
    this.shapeData = world_map;
}
}

Setting minimum and maximum values for zoom factor

The zooming range can be adjusted using the minZoom and maxZoom properties in zoomSettings. The minZoom value is set to 1 by default, and the maxZoom value is set to 10.

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,
        minZoom: 2,
        maxZoom: 12
    };
    this.shapeData = world_map;
}
}

Zooming with animation

To zoom in or zoom out the Maps with animation, use the animationDuration property in layers.

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' [animationDuration] = 'animationDuration'></e-layer>
</e-layers>
</ejs-maps>`
})
export class AppComponent implements OnInit {
public zoomSettings: object;
public shapeData: object;
public animationDuration: number;
ngOnInit(): void {
    this.zoomSettings = {
        enable: true,
        mouseWheelZoom:true
    };
    this.animationDuration = 500;
    this.shapeData = world_map;
}
}

Each shape in the Maps can be selected and deselected during interaction with the shapes. Selection is enabled by setting the enable property of selectionSettings to true.

The following properties are available to customize the selection 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 selected in Maps.
fill - Applies the color for the element that is selected.

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.
