- How to add spaces between characters in IText using FabricJS?
- In this tutorial, we will learn how to add spaces between characters in IText objects using FabricJS. The IText class was introduced in FabricJS version 1.4, which extends Fabric.Text and is used to create IText instances. IText instances allow us to freely select, cut, paste or add new text without additional configuration. There are also various supported key combinations and mouse/touch combinations to make text interactive that are not available in Text. However, Textbox based on IText allows us to resize the text rectangle and wrap it automatically. This is not the case for IText, as the height does not adjust based on line breaks. We can do this by using

- How to create a polygon with polylines using FabricJS?
- We can create a Polygon object by creating an instance of fabric.Polygon. A polygon object can be characterized as 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 such as angle, opacity, etc. Since Polygon extends fabric.Polyline, we can create a polygon instance using polyline brilliantly. Syntax newfabric.Polyline(points:Array,options:Object) Parameters points−This parameter accepts an Array, which represents the number of points that make up the polygon object.
