In this article, we are going to see how to lock vertically skewing of a Textbox canvas using FabricJS. The canvas Textbox means Textbox is movable and can be stretched according to requirement. Further, the Textbox can be customized when it comes to initial stroke color, height, width, fill color, or stroke width.
Approach:
- 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 Textbox.
- After this, we will initialize instances of Canvas and Textbox provided by FabricJS and set the lockSkewingY of canvas Textbox using lockSkewingY property and render the Textbox on the Canvas as given in the below example.
Syntax:
fabric.Textbox('text', {
lockSkewingY: boolean
});Parameters: This function accepts single parameters as mentioned above and described below:
- lockSkewingY: It specifies whether to lock vertically skewing of a Textbox canvas or not.
Example: This example uses FabricJS to set the vertically skewing of a canvas Textbox as given below.
