A polyline object can be characterised by 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. Serialization means converting the canvas into savable data which can be converted back into the canvas later. This data can be an object or JSON so that it can be stored on servers. We will use the toJSON() method to convert the canvas with Polyline object into JSON. Syntax toJSON(propertiesToInclude: Array): Object Parameters propertiesToInclude − This parameter accepts an Array ... Read More
A polyline object can be characterised by 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 will create a program where pressing a button will randomly generate a Polyline object and add it to our canvas for us. Syntax new fabric.Polyline(points: Array, options: Object) Parameters points − This parameter accepts an Array which denotes the array of points that make up the polyline object. options (optional) − This parameter is an Object which provides ...

We can create a Polyline object by creating an instance of fabric.Polyline. A polyline object can be characterised by 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. A star or pentagram consists of 10 isosceles triangles. Syntax new fabric.Polyline(points: Array, options: Object) Parameters points − This parameter accepts an Array which denotes the array of points that make up the polyline object. options (optional) − This parameter is an Object which provides additional customizations to ...

We can create a Polyline object by creating an instance of fabric.Polyline. A polyline object can be characterised by 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. In order to identify if the given object is of a Polyline instance, we use the isType method. This method checks if the object is of the specified type and returns a true or false value depending on that. Syntax isType(type: String): Boolean Here, type is the parameter that accepts ...

We can create a Polyline object by creating an instance of fabric.Polyline. A polyline object can be characterised by 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. For grouping multiple Polyline objects, we can use the toGroup() method. Syntax toGroup(): Fabric.Group Example 1: Creating an Instance of fabric.Polyline() and Adding it to our Canvas Before seeing how we can group multiple objects into one, let’s see a code example of how we can add a polyline object ...
