In this article, we are going to see how to set the lockScalingX 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.
Approach: 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 lock the horizontal scaling of the canvas Group using the lockScalingX property.
Syntax:
fabric.Group([canvas1, canvas2], {
lockScalingX: Boolean
});
Parameters: This property accepts a single parameter as mentioned above and described below:
- lockScalingX: It specifies whether to lock the horizontal scaling.
Below examples illustrate the use of Fabric.js Group lockScalingX 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 lockScalingX 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 ], { lockScalingX : true }); // Render the Group in canvas canvas.add(group); canvas.centerObject(group); </script> </body> </html> |
Output:
