Fabric.js Textbox fontWeight Property
In this article, we are going to see how to change the font weight of a canvas Textbox using FabricJS. The canvas means Textbox written is movable and can be stretched according to requirement.
Approach: To make this 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 Textbox. After this, we will initialize instances of Canvas and Textbox provided by FabricJS and use the fontWeight property to change the font-weight and render the Canvas on the Textbox as given in the example below.
Syntax:
fabric.Textbox('text', {
fontWeight: number
});Parameters: This function accepts one parameter as mentioned above and described below:
- fontWeight: It specifies the font-weight which can be bold, normal, 400, 500 etc.
Example: This example uses FabricJS to change font-weight of canvas textbox.
