Class: RegularShape

ol/style/RegularShape~RegularShape


import RegularShape from 'ol/style/RegularShape.js';

Set regular shape style for vector features. The resulting shape will be a regular polygon when radius is provided, or a star when both radius and radius2 are provided.

new RegularShape(options)

Name Type Description
fill Fill | undefined

Fill style.

points number

Number of points for stars and regular polygons. In case of a polygon, the number of points is the number of sides.

radius number

Radius of a regular polygon.

radius2 number | undefined

Second radius to make a star instead of a regular polygon.

angle number (defaults to 0)

Shape's angle in radians. A value of 0 will have one of the shape's points facing up.

displacement Array.<number> (defaults to [0, 0])

Displacement of the shape in pixels. Positive values will shift the shape right and up.

stroke Stroke | undefined

Stroke style.

rotation number (defaults to 0)

Rotation in radians (positive rotation clockwise).

rotateWithView boolean (defaults to false)

Whether to rotate the shape with the view.

scale number | Size (defaults to 1)

Scale. Unless two dimensional scaling is required a better result may be obtained with appropriate settings for radius and radius2.

declutterMode DeclutterMode | undefined

Declutter mode.

Subclasses

Extends

Pixel ratio.

Returns:
Image or Canvas element.

getOpacity(){number} inherited

Get the symbolizer opacity.

Returns:
Opacity.

getOrigin(){Array.<number>}

Get the origin of the symbolizer.

Returns:
Origin.

getPoints(){number}

Get the number of points for generating the shape.

Returns:
Number of points for stars and regular polygons.

getRadius(){number}

Get the (primary) radius for the shape.

Returns:
Radius.

getRadius2(){number | undefined}

Get the secondary radius for the shape.

Returns:
Radius2.

getRotateWithView(){boolean} inherited
