L.SVG

SVG

Although SVG is not available on IE7 and IE8, these browsers support VML, and the SVG renderer will fall back to VML in this case. VML was deprecated in 2012, which means VML functionality exists only for backwards compatibility with old versions of Internet Explorer.

Allows vector layers to be displayed with SVG. Inherits Renderer. Due to technical limitations, SVG is not available in all web browsers, notably Android 2.x and 3.x. Although SVG is not available on IE7 and IE8, these browsers support VML (a now deprecated technology), and the SVG renderer will fall back to VML in this case.

Usage example

Use SVG by default for all paths in the map:

var map = L.map('map', {
    renderer: L.svg();
});

Use a SVG renderer with extra padding for specific vector geometries:

var map = L.map('map');
var myRenderer = L.svg({ padding: 0.5 });
var line = L.polyline( coordinates, { renderer: myRenderer } );
var circle = L.circle( center, { renderer: myRenderer } );

Creation

Factory	Description
`L.svg(<Renderer options> options?)`	Creates a SVG renderer with the given options.

Options

▶ Options inherited from Renderer

Option	Type	Default	Description
`padding`	`Number`	`0.1`	How much to extend the clip area around the map view (relative to its size) e.g. 0.1 would be 10% of map view in each direction

▶ 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 Renderer

Event	Data	Description
`update`	`Event`	Fired when the renderer updates its bounds, center and zoom, for example when its map has moved

▶ 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

▶ 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(…)`

Functions

There are several static functions which can be called without instantiating L.SVG:

Function	Returns	Description
`create(<String> name)`	`SVGElement`	Returns a instance of SVGElement, corresponding to the class name passed. For example, using 'line' will return an instance of SVGLineElement.
`pointsToPath(<Point[]> rings, <Boolean> closed)`	`String`	Generates a SVG path string for multiple rings, with each ring turning into "M..L..L.." instructions
