dg-entrance

Allows to display an entrance to the building. The class supports simple animation and multiple inputs display. Objects of entrances themselves represent arrows which change their scale together with zooming, but not lower than the level 16, after which the arrows disappear from the map (until reaching an acceptable level of zooming).

DG.Entrance

Example of usage

Create and display the entrances to the building:

var options = {
    vectors: [
        'LINESTRING(82.897079 54.980906,82.897191 54.980844)',
        'LINESTRING(82.897933 54.980649,82.898045 54.980587)',
        'LINESTRING(82.897071 54.980122,82.897226 54.98013)',
        'LINESTRING(82.897354 54.979515,82.89741 54.979599)',
        'LINESTRING(82.898498 54.979826,82.898386 54.979889)',
    ],
};
DG.entrance(options).addTo(map).show(true);

Creation

Factory	Usage	Description
DG.Entrance( <Entrance options> options )	DG.entrance(…)	Creates an entrance object based on the provided options.

Options

Option	Type	Default	Description
vectors	Array	[]	(a required parameter)An array of vectors describing the entrances to the building. You can send several values in the array, if there is more than one entrance to the building. Each element should represent a string in WKT format: LINESTRING(lng0 lat0,lng1 lat1[,... lngN latN]), where the last coordinate pair should be a direct entrance point to the building, and the previous coordinates - be the route to this point. Throughout the route there should not be mutual intersections.
fillColor	String	#0085a0	The fill color of the arrows.
strokeColor	String	#ffffff	The outline color of the arrows.
enableAnimation	Boolean	true	Whether to animate the display of arrows when you change the zoom levels of the map and during the initial display.
interactive	Boolean	false	If the value is false, then the handler of the mouse actions is not called.
autoClose	Boolean	true	Whether to remove objects of entrances after adding new layers to the map.

Methods

Method	Returns	Description
addTo( <Map> map )	this	Adds the object of entrances to the map.
removeFrom( <Map> map )	this	Removes the object of entrances from the map.
show( <fitBounds> boolean )	this	Displays entrances on the map. If fitBounds is set to true, then the map boundaries (and zoom level) are adjusted so that the user could see all the entrances on one screen.
hide()	this	Hides entrances. The objects themselves are not deleted from the map and the entrances can be re-displayed by calling the show() method.
isShown()	Boolean	Returns true if the entrances are currently displayed on the map.
setFillColor()	String	Changes the fill color of the arrows.
setStrokeColor()	String	Changes the outline color of the arrows.
