How to flip a Textbox horizontally using FabricJS?

In this tutorial, we are going to learn how we can flip a Textbox object horizontally using FabricJS. We can customize, stretch or move around the text written in a textbox. In order to create a textbox, we will have to create an instance of fabric.Textbox class and add it to the canvas. We can flip a textbox object horizontally using the flipX property.

Syntax

new fabric.Textbox(text: String, { flipX: Boolean }: Object)

Parameters

text − This parameter accepts a String which is the text string that we want to display inside our textbox.
options (optional) − This parameter is an Object which provides additional customizations to our textbox. Using this parameter, properties such as colour, cursor, stroke width and a lot of other properties can be changed related to the object of which flipX is a property.

Options Keys

flipX − This property accepts a Boolean value which allows us to flip an object horizontally.

Example 1

Passing flipX as key with a ‘false’ value

Let’s see a code example that shows us the default orientation of a textbox object in FabricJS. Since we are passing the flipX property a False value, the text will not be flipped horizontally.

      // Initiate a canvas instance
      var canvas = new fabric.Canvas("canvas");
      canvas.setWidth(document.body.scrollWidth);
      canvas.setHeight(250);

      // Initiate a textbox object
      var textbox = new fabric.Textbox("Each day provides its own gifts.", {
         backgroundColor: "#e3dac9",
         width: 400,
         left: 70,
         top: 70,
         flipX: false,
      });

      // Create gradient fill
      textbox.set(
         "fill",
         new fabric.Gradient({
            type: "linear",
            coords: { x1: 0, y1: 0, x2: 100, y2: 0 },
               colorStops: [
                  { offset: 0, color: "#545a2c" },
                  { offset: 1, color: "#6495ed" },
               ],
            })
         );
      // Add it to the canvas
      canvas.add(textbox);
   </script>
</body>
</html>

Example 2

Passing the flipX property as key with a ‘true’ value

In this example, we have a textbox object of width 200px with a horizontal linear gradient fill. As we apply the flipX property to the textbox object, the text flips horizontally and thus we see that the gradient and the text has flipped as well.
