How to lock the vertical movement of Line using FabricJS?
In this tutorial, we are going to learn how to lock the vertical movement of Line 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. We can also specify whether we want line object to move only in the X-axis. This can be done by ...
