In this article, we are going to see how to set the visibility of a canvas Textbox using visible Property in FabricJS. The canvas means Textbox is movable and can be stretched according to requirements. Further, the Textbox can be customized when it comes to initial stroke color, fill color, stroke width, or size.
To make it 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 set the visibility of the canvas Textbox using visible property, and render the Textbox on the Canvas as given in the example below.
Syntax:
fabric.Textbox('text', {
visible: boolean
});
Parameters: This function accepts one parameter as mentioned above and described below:
- visible: It specifies the visibility of the object.
Example: This example uses FabricJS Textbox visible Property to set the visibility of the canvas textbox to false, so the text will not be visible.
