How to create an Object representation of a Line object using FabricJS?
In this tutorial, we are going to learn about how to create an Object representation of a Line object using FabricJS. A Line element is one of the basic elements provided in FabricJS. It is used for creating straight lines. Because line elements are geometrically one-dimensional and do not contain an interior, they are never filled. We can create a line object by creating an instance of fabric.Line, specifying the x and y coordinates of the line and adding it to the canvas. In order to create an Object representation of a Line object, we use the toObject method. ...
