L.Icon

Icon

Represents an icon to provide when creating a marker.

Usage example

var myIcon = L.icon({
    iconUrl: 'my-icon.png',
    iconSize: [38, 95],
    iconAnchor: [22, 94],
    popupAnchor: [-3, -76],
    shadowUrl: 'my-icon-shadow.png',
    shadowSize: [68, 95],
    shadowAnchor: [22, 94]
});
L.marker([50.505, 30.57], {icon: myIcon}).addTo(map);

L.Icon.Default extends L.Icon and is the blue icon Leaflet uses for markers by default.

Creation

Factory	Description
`L.icon(<Icon options> options)`	Creates an icon instance with the given options.

Options

Option	Type	Default	Description
`iconUrl`	`String`	`null`	(required) The URL to the icon image (absolute or relative to your script path).
`iconRetinaUrl`	`String`	`null`	The URL to a retina sized version of the icon image (absolute or relative to your script path). Used for Retina screen devices.
`iconSize`	`Point`	`null`	Size of the icon image in pixels.
`iconAnchor`	`Point`	`null`	The coordinates of the "tip" of the icon (relative to its top left corner). The icon will be aligned so that this point is at the marker's geographical location. Centered by default if size is specified, also can be set in CSS with negative margins.
`popupAnchor`	`Point`	`null`	The coordinates of the point from which popups will "open", relative to the icon anchor.
`shadowUrl`	`String`	`null`	The URL to the icon shadow image. If not specified, no shadow image will be created.
`shadowRetinaUrl`	`String`	`null`
`shadowSize`	`Point`	`null`	Size of the shadow image in pixels.
`shadowAnchor`	`Point`	`null`	The coordinates of the "tip" of the shadow (relative to its top left corner) (the same as iconAnchor if not specified).
`className`	`String`	`''`	A custom class name to assign to both icon and shadow images. Empty by default.

▶ Options inherited from Layer

Option	Type	Default	Description
`pane`	`String`	`'overlayPane'`	By default the layer will be added to the map's overlay pane. Overriding this option will cause the layer to be placed on another pane by default.

Events

▶ Events inherited from Layer

Event	Data	Description
`add`	`Event`	Fired after the layer is added to a map
`remove`	`Event`	Fired after the layer is removed from a map

▶ Popup events inherited from Layer

Event	Data	Description
`popupopen`	`PopupEvent`	Fired when a popup bound to this layer is opened
`popupclose`	`PopupEvent`	Fired when a popup bound to this layer is closed

▶ Tooltip events inherited from Layer

Event	Data	Description
`tooltipopen`	`TooltipEvent`	Fired when a tooltip bound to this layer is opened.
`tooltipclose`	`TooltipEvent`	Fired when a tooltip bound to this layer is closed.

Methods

Method	Returns	Description
`createIcon(<HTMLElement> oldIcon?)`	`HTMLElement`	Called internally when the icon has to be shown, returns a `<img>` HTML element styled according to the options.
`createShadow(<HTMLElement> oldIcon?)`	`HTMLElement`	As `createIcon`, but for the shadow beneath it.

▶ Popup methods inherited from Layer

Method	Returns	Description
`bindPopup(<String\|HTMLElement\|Function\|Popup> content, <Popup options> options?)`	`this`	Binds a popup to the layer with the passed `content` and sets up the neccessary event listeners. If a `Function` is passed it will receive the layer as the first argument and should return a `String` or `HTMLElement`.
`unbindPopup()`	`this`	Removes the popup previously bound with `bindPopup`.
`openPopup(<LatLng> latlng?)`	`this`	Opens the bound popup at the specificed `latlng` or at the default popup anchor if no `latlng` is passed.
`closePopup()`	`this`	Closes the popup bound to this layer if it is open.
`togglePopup()`	`this`	Opens or closes the popup bound to this layer depending on its current state.
`isPopupOpen()`	`boolean`	Returns `true` if the popup bound to this layer is currently open.
`setPopupContent(<String\|HTMLElement\|Popup> content)`	`this`	Sets the content of the popup bound to this layer.
`getPopup()`	`Popup`	Returns the popup bound to this layer.

▶ Tooltip methods inherited from Layer

Method	Returns	Description
`bindTooltip(<String\|HTMLElement\|Function\|Tooltip> content, <Tooltip options> options?)`	`this`	Binds a tooltip to the layer with the passed `content` and sets up the neccessary event listeners. If a `Function` is passed it will receive the layer as the first argument and should return a `String` or `HTMLElement`.
`unbindTooltip()`	`this`	Removes the tooltip previously bound with `bindTooltip`.
`openTooltip(<LatLng> latlng?)`	`this`	Opens the bound tooltip at the specificed `latlng` or at the default tooltip anchor if no `latlng` is passed.
`closeTooltip()`	`this`	Closes the tooltip bound to this layer if it is open.
`toggleTooltip()`	`this`	Opens or closes the tooltip bound to this layer depending on its current state.
`isTooltipOpen()`	`boolean`	Returns `true` if the tooltip bound to this layer is currently open.
`setTooltipContent(<String\|HTMLElement\|Tooltip> content)`	`this`	Sets the content of the tooltip bound to this layer.
`getTooltip()`	`Tooltip`	Returns the tooltip bound to this layer.

▶ Methods inherited from Layer

Method	Returns	Description
`addTo(<Map> map)`	`this`	Adds the layer to the given map
`remove()`	`this`	Removes the layer from the map it is currently active on.
`removeFrom(<Map> map)`	`this`	Removes the layer from the given map
`getPane(<String> name?)`	`HTMLElement`	Returns the `HTMLElement` representing the named pane on the map. If `name` is omitted, returns the pane for this layer.

▶ Methods inherited from Evented

Method	Returns	Description
`on(<String> type, <Function> fn, <Object> context?)`	`this`	Adds a listener function (`fn`) to a particular event type of the object. You can optionally specify the context of the listener (object the this keyword will point to). You can also pass several space-separated types (e.g. `'click dblclick'`).
`on(<Object> eventMap)`	`this`	Adds a set of type/listener pairs, e.g. `{click: onClick, mousemove: onMouseMove}`
`off(<String> type, <Function> fn?, <Object> context?)`	`this`	Removes a previously added listener function. If no function is specified, it will remove all the listeners of that particular event from the object. Note that if you passed a custom context to `on`, you must pass the same context to `off` in order to remove the listener.
`off(<Object> eventMap)`	`this`	Removes a set of type/listener pairs.
`off()`	`this`	Removes all listeners to all events on the object.
`fire(<String> type, <Object> data?, <Boolean> propagate?)`	`this`	Fires an event of the specified type. You can optionally provide an data object — the first argument of the listener function will contain its properties. The event might can optionally be propagated to event parents.
`listens(<String> type)`	`Boolean`	Returns `true` if a particular event type has any listeners attached to it.
`once(…)`	`this`	Behaves as `on(…)`, except the listener will only get fired once and then removed.
`addEventParent(<Evented> obj)`	`this`	Adds an event parent - an `Evented` that will receive propagated events
`removeEventParent(<Evented> obj)`	`this`	Removes an event parent, so it will stop receiving propagated events
`addEventListener(…)`	`this`	Alias to `on(…)`
`removeEventListener(…)`	`this`	Alias to `off(…)`
`clearAllEventListeners(…)`	`this`	Alias to `off()`
`addOneTimeEventListener(…)`	`this`	Alias to `once(…)`
`fireEvent(…)`	`this`	Alias to `fire(…)`
`hasEventListeners(…)`	`Boolean`	Alias to `listens(…)`

Icon.Default

A trivial subclass of Icon, represents the icon to use in Markers when no icon is specified. Points to the blue marker image distributed with Leaflet releases. In order to change the default icon, just change the properties of L.Icon.Default.prototype.options (which is a set of Icon options).

Option	Type	Default	Description
`imagePath`	`String`		`L.Icon.Default` will try to auto-detect the absolute location of the blue icon images. If you are placing these images in a non-standard way, set this option to point to the right absolute path.
