Fabric.js line backgroundColor Property

Last Updated : 20 Jan, 2021

In this article, we are going to see how to change the background color of the canvas line using FabricJS. The canvas line means the line is movable and can be stretched according to requirements. Further, the line 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 line. After this, we will initialize instances of Canvas and line provided by FabricJS and change the background color of the canvas line using backgroundColor property and render on the Canvas as given in the example below.

Syntax:

fabric.line({
    backgroundColor : 'string'
});

Parameters: This property accept a single parameter as mentioned above and described below:

backgroundColor: It is the string that specifies the background color.

Example: This example uses FabricJS to change the background color of the line canvas.
