In this article, we are going to see how to set the dash pattern of controlling corners of 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.
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 a dash pattern of controlling corners of canvas ellipse using cornerDashArray property and render the Ellipse on the Canvas as given in the below example.
Syntax:
fabric.Ellipse({
rx: number,
ry: number,
cornerDashArray: array
});
Parameters: This function accept three parameters as mentioned above and described below:
- rx: This parameter defines the horizontal radius.
- ry: This parameter defines the vertical radius.
- cornerDashArray: This parameter defines the dash pattern of the controlling corners.
Program: This example uses FabricJS to set a dashed pattern of controlling corners of the canvas-like ellipse as given below. You have to click on the object to see the dash pattern of controlling corners.
