maxLines number | undefined <optional>

The maximum number of meridians and parallels from the center of the map. The default value is 100, which means that at most 200 meridians and 200 parallels will be displayed. The default value is appropriate for conformal projections like Spherical Mercator. If you increase the value more lines will be drawn and the drawing performance will decrease.

strokeStyle ol.style.Stroke | undefined <optional>

The stroke style to use for drawing the graticule. If not provided, the lines will be drawn with rgba(0,0,0,0.2), a not fully opaque black.

targetSize number | undefined <optional>

  }),
  stroke: new ol.style.Stroke({
    color: 'rgba(255,255,255,1)',
    width: 3
  })
});

Note that the default's textBaseline configuration will not work well for lonLabelPosition configurations that position labels close to the top of the viewport.

latLabelStyle ol.style.Text | undefined <optional>

Latitude label text style. The default is

new ol.style.Text({
  font: '12px Calibri,sans-serif',
  textAlign: 'end',

    width: 3
  })
});

Note that the default's textAlign configuration will not work well for latLabelPosition configurations that position labels close to the left of the viewport.

olx.LayerRendererPlugin{Object}

Properties:
Name Type Description
handles function

Determine if this renderer handles the provided layer. Required.

create function

Create a layer renderer. Required.

olx.LogoOptions{Object}

Name Type Description
href string

Link url for the logo. Will be followed when the logo is clicked. Required.

src string

Image src for the logo. Required.

olx.MapOptions{Object}

Object literal with config options for the map.

Properties:
Name Type Argument Description
controls ol.Collection.<ol.control.Control> | Array.<ol.control.Control> | undefined <optional>

Controls initially added to the map. If not specified, ol.control.defaults() is used.

pixelRatio number | undefined <optional>

The ratio between physical pixels and device-independent pixels (dips) on the device. If undefined then it gets set by using window.devicePixelRatio.

interactions ol.Collection.<ol.interaction.Interaction> | Array.<ol.interaction.Interaction> | undefined <optional>

Interactions that are initially added to the map. If not specified, ol.interaction.defaults() is used.

keyboardEventTarget Element | Document | string | undefined <optional>

The element to listen to keyboard events on. This determines when the KeyboardPan and KeyboardZoom interactions trigger. For example, if this option is set to document the keyboard interactions will always trigger. If this option is not specified, the element the library listens to keyboard events on is the map target (i.e. the user-provided div for the map). If this is not document the target element needs to be focused for key events to be emitted, requiring that the target element has a tabindex attribute.

layers Array.<ol.layer.Base> | ol.Collection.<ol.layer.Base> | undefined <optional>

Layers. If this is not defined, a map with no layers will be rendered. Note that layers are rendered in the order supplied, so if you want, for example, a vector layer to appear on top of a tile layer, it must come after the tile layer.

loadTilesWhileAnimating boolean | undefined <optional>

When set to true, tiles will be loaded during animations. This may improve the user experience, but can also make animations stutter on devices with slow memory. Default is false.

loadTilesWhileInteracting boolean | undefined <optional>

When set to true, tiles will be loaded while interacting with the map. This may improve the user experience, but can also make map panning and zooming choppy on devices with slow memory. Default is false.

logo boolean | string | olx.LogoOptions | Element | undefined <optional>

The map logo. A logo to be displayed on the map at all times. If a string is provided, it will be set as the image source of the logo. If an object is provided, the src property should be the URL for an image and the href property should be a URL for creating a link. If an element is provided, the element will be used. To disable the map logo, set the option to false. By default, the OpenLayers logo is shown.

moveTolerance number | undefined <optional>

The minimum distance in pixels the cursor must move to be detected as a map move event instead of a click. Increasing this value can make it easier to click on the map. Default is 1.

overlays ol.Collection.<ol.Overlay> | Array.<ol.Overlay> | undefined <optional>

Overlays initially added to the map. By default, no overlays are added.

renderer ol.renderer.Type | Array.<ol.renderer.Type> | undefined <optional>

Renderer. By default, Canvas and WebGL renderers are tested for support in that order, and the first supported used. Specify a ol.renderer.Type here to use a specific renderer. Note that the Canvas renderer fully supports vector data, but WebGL can only render Point geometries.

target Element | string | undefined <optional>

The container for the map, either the element itself or the id of the element. If not specified at construction time, ol.Map#setTarget must be called for the map to be rendered.

view ol.View | undefined <optional>

The map's view. No layer sources will be fetched unless this is specified at construction time or through ol.Map#setView.

position ol.Coordinate | undefined <optional>

The overlay position in map projection.

positioning ol.OverlayPositioning | string | undefined <optional>

Defines how the overlay is actually positioned with respect to its position property. Possible values are 'bottom-left', 'bottom-center', 'bottom-right', 'center-left', 'center-center', 'center-right', 'top-left', 'top-center', and 'top-right'. Default is 'top-left'.

stopEvent boolean | undefined <optional>

Whether event propagation to the map viewport should be stopped. Default is true. If true the overlay is placed in the same container as that of the controls (CSS class name ol-overlaycontainer-stopevent); if false it is placed in the container with CSS class name ol-overlaycontainer.

insertFirst boolean | undefined <optional>

Whether the overlay is inserted first in the overlay container, or appended. Default is true. If the overlay is placed in the same container as that of the controls (see the stopEvent option) you will probably set insertFirst to true so the overlay is displayed below the controls.

autoPan boolean | undefined <optional>

If set to true the map is panned when calling setPosition, so that the overlay is entirely visible in the current viewport. The default is false.
