Class: Style

ol/style/Style~Style


import Style from 'ol/style/Style';

Container for vector feature rendering styles. Any changes made to the style or its children through set*() methods will not take effect until the feature or layer that uses the style is re-rendered.

Feature styles

If no style is defined, the following default style is used:

 import {Fill, Stroke, Circle, Style} from 'ol/style';

 var fill = new Fill({
   color: 'rgba(255,255,255,0.4)'
 });
 var stroke = new Stroke({
   color: '#3399CC',
   width: 1.25
 });
 var styles = [
   new Style({
     image: new Circle({
       fill: fill,
       stroke: stroke,
       radius: 5
     }),
     fill: fill,
     stroke: stroke
   })
 ];

A separate editing style has the following defaults:

 import {Fill, Stroke, Circle, Style} from 'ol/style';
 import GeometryType from 'ol/geom/GeometryType';

 var white = [255, 255, 255, 1];
 var blue = [0, 153, 255, 1];
 var width = 3;
 styles[GeometryType.POLYGON] = [
   new Style({
     fill: new Fill({
       color: [255, 255, 255, 0.5]
     })
   })
 ];
 styles[GeometryType.MULTI_POLYGON] =
     styles[GeometryType.POLYGON];
 styles[GeometryType.LINE_STRING] = [
   new Style({
     stroke: new Stroke({
       color: white,
       width: width + 2
     })
   }),
   new Style({
     stroke: new Stroke({
       color: blue,
       width: width
     })
   })
 ];
 styles[GeometryType.MULTI_LINE_STRING] =
     styles[GeometryType.LINE_STRING];
 styles[GeometryType.POINT] = [
   new Style({
     image: new Circle({
       radius: width * 2,
       fill: new Fill({
         color: blue
       }),
       stroke: new Stroke({
         color: white,
         width: width / 2
       })
     }),
     zIndex: Infinity
   })
 ];
 styles[GeometryType.MULTI_POINT] =
     styles[GeometryType.POINT];
 styles[GeometryType.GEOMETRY_COLLECTION] =
     styles[GeometryType.POLYGON].concat(
         styles[GeometryType.LINE_STRING],
         styles[GeometryType.POINT]
     );

new Style(opt_options)

Name Type Description
options

Style options.

Name Type Description
geometry string | module:ol/geom/Geometry~Geometry | module:ol/style/Style~GeometryFunction

Feature property or geometry or function returning a geometry to render for this style.

fill module:ol/style/Fill~Fill

Fill style.

image module:ol/style/Image~ImageStyle

Image style.

renderer module:ol/style/Style~RenderFunction

zIndex number

Z index.

Methods

Clones the style.

Returns:
The cloned style.

Get the fill style.

Returns:
Fill style.

Get the geometry to be rendered.

Returns:
Feature property or geometry or function that returns the geometry that will be rendered with this style.

Get the function used to generate a geometry for rendering.

Returns:
Function that is called with a feature and returns the geometry to render instead of the feature's geometry.

Get the image style.

Returns:
Image style.

Get the custom renderer function that was configured with #setRenderer or the renderer constructor option.

Returns:
Custom renderer function.

Returns:
Text style.

getZIndex(){number|undefined}

Get the z-index for the style.

Returns:
ZIndex.
