In this tutorial, we are going to set the border scale factor of Rectangle using FabricJS. Rectangle is one of the various shapes provided by FabricJS. In order to create a rectangle, we will have to create an instance of fabric.Rect class and add it to the canvas.We can use the borderScaleFactor property which specifies the scale factor of the object's controlling borders.Syntaxnew fabric.Rect({ borderScaleFactor: Number }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our rectangle. Using this parameter, properties such as colour, cursor, stroke width and a lot of other properties can be ... Read More

In this tutorial, we are going to learn how to lock the rotation of a Rectangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a rectangle object in the canvas, we can also specify whether we want it to rotate or not. This can be done by using the lockRotation property.Syntaxnew fabric.Rect({ lockRotation : Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our rectangle. Using this parameter, properties such as colour, cursor, stroke width, and a lot of other properties can be changed related to the object ... Read More

In this tutorial, we are going to learn how to lock the horizontal skewing of a Rectangle using FabricJS. Just as we can specify the position, colour, opacity and dimension of a rectangle object in the canvas, we can also specify whether we want to stop skewing an object horizontally. This can be done by using the lockSkewingX property.Syntaxnew fabric.Rect({ lockSkewingX : Boolean }: Object)ParametersOptions (optional) − This parameter is an Object which provides additional customizations to our rectangle. Using this parameter, properties such as colour, cursor, stroke width, and a lot of other properties can be changed related to ... Read More
