- How to get the coordinates of a Line object using FabricJS?
- In this tutorial, we will show how to get the coordinates of a line using FabricJS. Line element is one of the basic elements provided in FabricJS. It is used to create straight lines. Since line elements are geometrically one-dimensional and contain no interiors, 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. To get the coordinates of a Line object, we use the getCoords method. Syntax getCoords():Array Example using getCoords method Let us look at a code example to see the output recorded when the getCoords method is executed. ge
