Fabric.js Textbox strokeDashOffset Property

  • Last Updated : 20 Jan, 2021

In this article, we are going to see how to set the stroke offset to the canvas Textbox using FabricJS. The canvas Textbox means the Textbox is movable and can be stretched according to requirements. Further, the Textbox 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 that will contain the textbox. After this, we will initialize instances of Canvas and Textbox provided by FabricJS and create a stroke using stroke property, and further use the strokeDashOffset property to add stroke offset and render the canvas on the textbox as given in the below example.

Syntax:

fabric.Textbox('text', {
   strokeDashOffset: number
});

Parameters: This function accepts one parameter as mentioned above and described below.

  • strokeDashOffset: It specifies the amount of offset of stroke.

Example: This example uses FabricJS library to set the stroke dashed offset to the canvas textbox as given below.

            'A Computer Science Portal', {
            width: 500,
            strokeDashOffset: 10,
            stroke: 'green'
        });
  
        // Render the Textbox in canvas 
        canvas.add(text);
        canvas.centerObject(text);
    </script>
