In this article, we are going to see how to set the border color of a canvas image using FabricJS. The canvas means the image is movable and can be stretched according to requirement. Further, the image can be customized when it comes to angle, stroke width, padding, etc.
To make this 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 our image. Further, we will create an img element which contains the image to be added inside the canvas and set the style attribute to display: none; because we don’t want the image to be visible outside the canvas. After this, we will initialize instances of Canvas and Image provided by FabricJS and render the Image on the Canvas and set the border color of the canvas image using borderColor property as given in the example below.
Syntax:
fabric.Image({
image,
borderColor: string
});
Parameters: This function accepts two parameters as mentioned above and described below:
- image: It specifies the image object.
- borderColor: It specifies the border color of the image.
Example: This example uses FabricJS to set the border color of the canvas image. Note that you have to click on the image object to see the border color.
