Layer Style Objects

This object defines the styling for a "vector" layer. The "style" property can contain one of these objects or an array of many of these objects. When multiple styles are defined, then each feature in the layer is rendered in each style successively. This is a way to build more complex styles.

If a point feature is being rendered, the "marker..." properties are used. If the "markerUrl" property isn’t defined, then a circle is rendered instead, using the "stroke..." and "fill..." properties. The circle radius will be half of the "strokeWidth" property.

A style object contains is defined with these properties, which have these default values. Click on a property name for more information:
