Leaflet.draw 0.2.0 requires Leaflet 0.6 or higher.

#Leaflet.draw Adds support for drawing and editing vectors and markers on Leaflet maps. Check out the demo

Upgrading from Leaflet.draw 0.1

Leaflet.draw 0.2.0 changes a LOT of things from 0.1. Please see BREAKING CHANGES for how to upgrade.

// create a map in the "map" div, set the view to a given place and zoom
var map = L.map('map', {drawControl: true}).setView([51.505, -0.09], 13);

// add an OpenStreetMap tile layer
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

Adding the edit toolbar

To use the edit toolbar you must initialise the Leaflet.draw control and manually add it to the map.

// create a map in the "map" div, set the view to a given place and zoom
var map = L.map('map').setView([51.505, -0.09], 13);

// add an OpenStreetMap tile layer
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
    attribution: '&copy; <a href="http://osm.org/copyright">OpenStreetMap</a> contributors'
}).addTo(map);

// Initialize the FeatureGroup to store editable layers
var drawnItems = new L.FeatureGroup();
map.addLayer(drawnItems);

// Initialize the draw control and pass it the FeatureGroup of editable layers
var drawControl = new L.Control.Draw({
	edit: {
		featureGroup: drawnItems
	}
});
map.addControl(drawControl);

The key here is the featureGroup option. This tells the plugin which FeatureGroup that contains the layers that should be editable.

Events

Once you have successfully added the Leaflet.draw plugin your map you will want to respond to the different actions users can do. The following events will be triggered on the map:

draw:created

Property	Type	Description
layer	Polyline/Polygon/Rectangle/Circle/Marker	Layer that was just created.
layerType	String	The type of layer this is. One of: `polyline`, `polygon`, `rectangle`, `circle`, `marker`

Triggered when a new vector or marker has been created.

map.on('draw:created', function (e) {
	var type = e.layerType,
		layer = e.layer;

	if (type === 'marker') {
		// Do marker specific actions
	}

	// Do whatever else you need to. (save to db, add to map etc)
	map.addLayer(layer);
});

draw:edited

	layers.eachLayer(function (layer) {
		//do whatever you want, most likely save back to db
	});
});

## Advanced options

You can configure the plugin by using the different options listed here.

Control.Draw

These options make up the root object that is used when initializing the Leaflet.draw control.

Option	Type	Default	Description
position	String	`'topleft'`	The initial position of the control (one of the map corners). See control positions.
draw	DrawOptions	`{}`	The options used to configure the draw toolbar.
edit	EditOptions	`false`	The options used to configure the edit toolbar.

### DrawOptions

These options will allow you to configure the draw toolbar and it's handlers.

Option	Type	Default	Description

Draw handler options

The following options will allow you to configure the individual draw handlers.

#### PolylineOptions

Polyline and Polygon drawing handlers take the same options.

Option	Type	Default	Description
allowIntersection	Bool	`true`	Determines if line segements can cross.
drawError	Object	See code	Configuration options for the error that displays if an intersection is detected.

metric	Bool	`true`	Determines which measurement system (metric or imperial) is used.
zIndexOffset	Number	`2000`	This should be a high number to ensure that you can draw over all other layers on the map.
repeatMode	Bool	`false`	Determines if the draw tool remains enabled after drawing a shape.

#### PolygonOptions

Polygon options include all of the Polyline options plus the option to show the approximate area.

Option	Type	Default	Description
showArea	Bool	`false`	Show the area of the drawn polygon in m², ha or km². The area is only approximate and become less accurate the larger the polygon is.

#### RectangleOptions

### EditOptions

These options will allow you to configure the draw toolbar and its handlers.

Option	Type	Default	Description
featureGroup	Leaflet FeatureGroup	`null`	This is the FeatureGroup that stores all editable shapes. THIS iS REQUIRED FOR THE EDIT TOOLBAR TO WORK
edit	EditHandlerOptions	`{ }`	Edit handler options. Set to `false` to disable handler.

#### DeleteHandlerOptions

Option	Type	Default	Description

#### Customizing language and text in Leaflet.draw

Leaflet.draw uses the L.drawLocal configuration object to set any text used in the plugin. Customizing this will allow support for changing the text or supporting another language.

See Leaflet.draw.js for the default strings.

E.g.

// Set the button title text for the polygon button
L.drawLocal.draw.toolbar.buttons.polygon = 'Draw a sexy polygon!';

// Set the tooltip start text for the rectangle
L.drawLocal.draw.handlers.rectangle.tooltip.start = 'Not telling...';

## Common tasks

The following examples outline some common tasks.

Example Leaflet.draw config

The following example will show you how to:

Change the position of the control's toolbar.
Customize the styles of a vector layer.
Use a custom marker.
Disable the delete functionality.

var cloudmadeUrl = 'http://{s}.tile.cloudmade.com/BC9A493B41014CAABB98F0471D759707/997/256/{z}/{x}/{y}.png',
	cloudmade = new L.TileLayer(cloudmadeUrl, {maxZoom: 18}),
	map = new L.Map('map', {layers: [cloudmade], center: new L.LatLng(-37.7772, 175.2756), zoom: 15 });

var editableLayers = new L.FeatureGroup();
map.addLayer(editableLayers);

var MyCustomMarker = L.Icon.extend({
	options: {
		shadowUrl: null,
		iconAnchor: new L.Point(12, 12),
		iconSize: new L.Point(24, 24),
		iconUrl: 'link/to/image.png'
	}
});

var options = {
	position: 'topright',
	draw: {
		polyline: {
			shapeOptions: {
				color: '#f357a1',
				weight: 10
			}
		},
		polygon: {
			allowIntersection: false, // Restricts shapes to simple polygons
			drawError: {
				color: '#e1e100', // Color the shape will turn when intersects
				message: '<strong>Oh snap!<strong> you can\'t draw that!' // Message that will show when intersect
			},
			shapeOptions: {
				color: '#bada55'
			}
		},
		circle: false, // Turns off this drawing tool
		rectangle: {
			shapeOptions: {
				clickable: false
			}
		},
		marker: {
			icon: new MyCustomMarker()
		}
	},
	edit: {
		featureGroup: editableLayers, //REQUIRED!!
		remove: false
	}
};

var drawControl = new L.Control.Draw(options);
map.addControl(drawControl);

map.on('draw:created', function (e) {
	var type = e.layerType,
		layer = e.layer;

	if (type === 'marker') {
		layer.bindPopup('A popup!');
	}

	drawnItems.addLayer(layer);
});

Disabling a toolbar

If you do not want a particular toolbar in your app you can turn it off by setting the toolbar to false.

var drawControl = new L.Control.Draw({
	draw: false,
	edit: {
		featureGroup: editableLayers
	}
});

Disabling a toolbar item

If you want to turn off a particular toolbar item, set it to false. The following disables drawing polygons and markers. It also turns off the ability to edit layers.

var drawControl = new L.Control.Draw({
	draw: {
		polygon: false,
		marker: false
	},
	edit: {
		featureGroup: editableLayers,
		edit: false
	}
});

Changing a drawing handlers options

You can change a draw handlers options after initialization by using the setDrawingOptions method on the Leaflet.draw control.

E.g. to change the colour of the rectangle:

drawControl.setDrawingOptions({
    rectangle: {
    	shapeOptions: {
        	color: '#0000FF'
        }
    }
});

Creating a custom build

If you only require certain handlers (and not the UI), you may wish to create a custom build. You can generate the relevant jake command using the build html file.

See edit handlers example which uses only the edit handlers.

## Thanks

Thanks so much to @brunob, @tnightingale, and @shramov. I got a lot of ideas from their Leaflet plugins.

All the contributors and issue reporters of this plugin rock. Thanks for tidying up my mess and keeping the plugin on track.

The icons used for some of the toolbar buttons are either from http://glyphicons.com/ or inspired by them. <3 Glyphicons!

Finally, @mourner is the man! Thanks for dedicating so much of your time to create the gosh darn best JavaScript mapping library around.
