In this readme
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(L.Draw.Event.CREATED, function (e) {
var type = e.layerType,
layer = e.layer;
if (type === 'marker') {
layer.bindPopup('A popup!');
}
editableLayers.addLayer(layer);
});Changing a drawing handlers options
You can change a draw handlers options after initialisation 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'
}
}
});Contributing

Thanks
Touch friendly version of Leaflet.draw was created by Michael Guild (https://github.com/michaelguild13).
The touch support was initiated due to a demand for it at National Geographic for their Map Maker Projected (http://mapmaker.education.nationalgeographic.com/) that was created by Michael Guild and Daniel Schep (https://github.com/dschep)
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.
