Fabric.js Image hasRotatingPoint Property

Fabric.js is a JavaScript library that is used to work with canvas. The canvas image is one of the class of fabric.js that is used to create image instances. The canvas image means the Image is movable and can be stretched according to requirement. The hasRotatingPoint property of the image is used to enable or disable the controlling rotating point i.e. making it invisible.

Approach: First import the fabric.js library. After importing the library, create a canvas block in the body tag which will contain the image. After this, initialize an instance of Canvas and image class provided by Fabric.JS and then use the hasRotatingPoint property to enable or disable the rotating point of the canvas image. After this render the image on the canvas.

Syntax:

fabric.Image(image, {
    hasRotatingPoint : Boolean
});

Parameters: This function takes two parameters as mentioned above and described below:

  • image: This parameter takes the image element.
  • hasRotatingPoint: This parameter takes a boolean value to enable or disable the rotating point of the canvas image.

Example: This example uses FabricJS to disable the rotating point of the canvas image as shown in the below given example.
