In this article, we are going to see how to disable borders of the canvas ellipse using FabricJS. The canvas means ellipse is movable and can be stretched according to requirement. Further, the ellipse can be customized when it comes to initial stroke color, fill color, stroke width, or radius.
Approach: 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 that will contain our ellipse. After this, we will initialize instances of Canvas and Ellipse provided by FabricJS and disable borders of the canvas ellipse using hasBorders property and render the Ellipse on the Canvas as given in the below example.
Syntax:
fabric.Ellipse({
rx: number,
ry: number,
hasBorders: boolean
});
Parameters: This function accepts three parameters as mentioned above and described below:
- rx: It specifies the horizontal radius.
- ry: It specifies the vertical radius.
- hasBorders: It specifies whether to make borders visible or not.
Program: This example uses FabricJS to disable borders of the canvas ellipse as given below.
