We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized by any closed shape consisting of a set of connected straight line segments. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. We can return the dataless object representation of a polygon by using the toDatalessObject method. This method returns the object representation of a polygon instance. Syntax toDatalessObject( propertiesToInclude: Array ): Object Parameters propertiesToInclude (optional) − This parameter accepts an Array which allows us to ... Read More
