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. De-serialization is the process of converting back JSON or object to the canvas. We will use the loadfromJSON() method to de-serialize the canvas with Polyline object from JSON. Syntax ... Read More

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 check if a Polyline object intersects with another object, we use the intersectsWithObject method. This method checks whether the object that is passed to it, intersects with the polyline object. Syntax intersectsWithObject(other: Object, absolute: Boolean, calculate: Boolean ): Boolean Parameters other − This parameter accepts an ... Read More

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 add transition-in and transition-out animation, we can use the left property in conjunction with animate method. Syntax animate(property: String | Object, value: Number | Object): fabric.Object | fabric.AnimationContext | Array. Parameters property − This property accepts a String or Object value which determines which properties ... Read More

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. Since blur is not available in FabricJS itself, we will use CSS to add blur-in and blur-out animation to our Polyline. Syntax filter: blur(Xpx) Here, "X" is the property that accepts a Number value which determines the amount of blur to apply. Example 1: Adding blur-in animation to a polyline ... Read More

We can create a Polyline object by creating an instance of fabric.Polyline while fabric.Polygon can be used to create a Polygon instance. 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 polygon always connects the first point to the last to make a closed area while a polyline doesn’t. This can be proved by the examples given below. Syntax new fabric.Polyline(points: Array, options: Object) Parameters points − This ... Read More

We can add default vertical scaling to a text canvas using Fabric.js by first creating a text object and then setting the "scaleY" property to the desired scaling value. Additionally, we can use the "setCoords()" method to update the object's coordinates to reflect the scaling change. Before diving into the approach let’s just have a quick look what Fabric.js is − What is Fabric.js? Fabric.js is a JavaScript library for creating and manipulating HTML5 canvas elements. It allows developers to create and manipulate canvas elements using an object-oriented API, making it easy to add, edit, and delete shapes, text, images, ... Read More

To add a line through to a canvas-type text using Fabric.js, you can use the "set('textDecoration', 'line-through')" method on the text object. This method allows you to set the textDecoration property of the text object to "line-through", which will add a line through the text. Finally, you need to call the "renderAll()" method to update the canvas with the new text decoration. Fabric.js is a JavaScript library for working with object-oriented canvas graphics. It provides an easy-to-use API for creating and manipulating canvas elements, such as shapes, text, and images. With Fabric.js, you can create complex canvas graphics and animations ... 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. 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 ...
