Fabric.js | Rect height Property

In this article, we are going to see how to set the height of the object containing the canvas rectangle using FabricJS. The canvas rectangle means rectangle is movable and can be stretched according to requirement. Further, the rectangle 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 rectangle. After this, we will initialize instances of Canvas and Rect provided by FabricJS and set the height of the rectangle using height property and render the Rect on the Canvas as given below example.

Syntax:

fabric.Rect({
    width: number,
    height: number,
    height: number
});

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

width: It specifies the width of rectangle.
height: It specifies the height of rectangle.
height: It specifies the height of the object.

Example: This example uses FabricJS to set the height of a canvas rectangle.
