In this article, we are going to see how to set the lockScalingY of a Group of the canvas using Fabric.js. The Group in Fabric.js is movable and can be stretched according to requirements. Further, the Group can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
To make it possible we are going to use a JavaScript library called Fabric.js. After importing the library, we will create a canvas block in the body tag that will contain the Group. After this, we will initialize instances of Canvas and Group provided by Fabric.js and see if the option set to true will lock the vertical scaling in the canvas Group using the lockScalingY property.
Syntax:
fabric.Group([canvas1, canvas2], {
lockScalingY: Boolean
});
Parameters: This property accepts a single parameter as mentioned above and described below:
- lockScalingY: It specifies if the option set to true will lock the vertical scaling. It contains a boolean value.
Below examples illustrate the use of Fabric.js Group lockScalingY property in JavaScript:
Example:
HTML
<!DOCTYPE html> <html>   <head>   <!-- FabricJS CDN -->  <script src=   </script>   </head>   <body>     <div style="text-align: center;width: 400px;">       <h1 style="color: green;">           neveropen       </h1>       <b>           Fabric.js | Group lockScalingY Property       </b>     </div>         <div style="text-align: center;">       <canvas id="canvas" width="500" height="300"      style="border:1px solid green;">       </canvas>     </div>         <script>         // Initiate a Canvas instance       var canvas = new fabric.Canvas("canvas");               // Initiate a circle instance       var circle = new fabric.Circle({         radius: 100,         fill: 'lightgreen',         scaleY: 0.6,         originX: 'center',         originY: 'center'       });         // Initiate a text instance       var text = new fabric.Text('neveropen', {         fontSize: 25,         originX: 'center',         originY: 'center'       });         // Initiate a Group instance       var group = new fabric.Group([ circle, text ], {          lockScalingY : true       });         // Render the Group in canvas       canvas.add(group);         canvas.centerObject(group);   </script> </body>   </html> |
