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. A FabricJS object is cached on an additional canvas for saving time during re-using the object. In order to switch off object caching for Polygon object we use the objectCaching property. Syntax new fabric.Polygon( points: Array, { objectCaching: Boolean }: Object ) Parameters ... Read More

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 straighten a rotated Polygon object by using the straighten method. The straighten method straightens an object by rotating it from its current angle to 0, 90, 180 or 270 etc., depending on the angle that is closer. Syntax straighten(): fabric.Object Example ...

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. Serialization is the process of converting an object into a format which is suitable for transfer over a network, which in this case is the object representation. In order to create an Object representation of a Polygon object, we use the toObject method. This method ... Read More

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

Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. Syntax new fabric.Polygon( points: Array, options: Object ) Parameters points − This parameter accepts an Array which denotes the array of points that make up the polygon object. options (optional)− This parameter is an Object which provides additional customizations to our object. Using ... Read More

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. Syntax canvas.on("mouse:wheel", callbackFunction); Example 1: Applying zoom Controls on a Polygon Object Let’s see a code example of how we can apply zoom controls on a Polygon object. We can move the mouse wheel to zoom-in or zoom-out. We have added event listener to ... Read More

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 use the skewing event to demonstrate how a polygon object reacts to the user while being skewed via controls. Syntax polygon.on("skewing", callbackFunction); Example 1: Displaying how the Object Reacts to the skewing Event Let’s see a code example of how the polygon object ... Read More

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 use the selected and deselected events to demonstrate how to make a polygon object react on user’s selection and deselection of object. Syntax polygon.on("selected", callbackFunction); polygon.on("deselected", callbackFunction); Example 1: Displaying how the Object Reacts to the selected Event Let’s see a code example ... Read More
