Fabric.js Ellipse height Property

  • Last Updated : 25 Jan, 2021

In this article, we are going to see how to set the height of the object containing the canvas Ellipse using FabricJS. The canvas Ellipse means Ellipse is movable and can be stretched according to requirement. Further, the Ellipse 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 FabricJS. After importing the library, we will create a canvas block in the body tag which will contain the Ellipse. After this, we will initialize the instances of Canvas and Ellipse provided by FabricJS and set the height of the Ellipse using height property and render the Ellipse on the Canvas as given below example.

Syntax:

fabric.Ellipse({
   rx: number,
   ry: number,
   fill: string,
   height: number
});

Parameters: This function accept four parameters as mentioned above and described below:

  • rx: It specifies the horizontal radius.
  • ry: It specifies the vertical radius.
  • fill: It specifies the color to fill the ellipse.
  • height: It specifies the height of the object.

Example: This example uses FabricJS to set the height of a canvas Ellipse.
