Fabric.js Ellipse width Property

  • Last Updated : 04 Feb, 2021

In this article, we are going to see how to set the width of a canvas Ellipse using FabricJS. The canvas means Ellipse is movable and can be stretched according to requirements. Further, the Ellipse can be customized when it comes to initial stroke color, fill color, stroke width, or size.

To make it possible we are going to use a JavaScript library called FabricJS. After importing the library using CDN, we will create a canvas block in the body tag which will contain our Ellipse. After this, we will initialize instances of Canvas and Ellipse provided by FabricJS and set the width of the canvas Ellipse using width property, and render the Ellipse on the Canvas as given in the example below.

Syntax:

fabric.Ellipse({
   rx: number,
   ry: number,
   stroke: string,
   width: number
});

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

  • rx: It specifies the horizontal radius.
  • ry: It specifies the vertical radius.
  • stroke: It specifies the stroke color.
  • width: It specifies the width of ellipse box.

Example: This example uses FabricJS to set width of the canvas ellipse.

            ry: 75,
            fill: '',
            stroke: 'green',
            width: 300

        canvas.centerObject(ellipse);
