image
Returns image expression for use in '*-pattern' and 'icon-image' layer properties. Compared to string literals that can be used to represent an image, image expression allows to determine an image's availability at runtime, thus, can be used in conditional coalesce operator.
Example usage:
SymbolLayer symbolLayer = new SymbolLayer("layer-id", "source-id");
symbolLayer.setProperties(
iconImage(image(get("key-to-feature")))
);
