How to make the controlling corners of a Textbox transparent using FabricJS?
In this tutorial, we are going to learn how to make the controlling corners of Textbox transparent 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. The transparentCorners property allows us to make the controlling corners of Textbox transparent.
Syntax
new fabric.Textbox(text: String, { transparentCorners: 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 transparentCorners is a property.
Options Keys
transparentCorners − This property accepts a Boolean value which allows us to render the controlling corners of an object as transparent. Its default value is true.
Example 1
Passing transparentCorners property as key with a "false" value
Let’s see a code example to create a textbox object with controlling corners that are not transparent. To achieve this, we need to pass the transparentCorners property a False value.
<!DOCTYPE html> <html> <head> <!-- Adding the Fabric JS Library--> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script> </head> <body> <h2>Passing transparentCorners property as key with a ‘false’ value</h2> <p>You can select the textbox to see that the controlling corners are opaque </p> <canvas id="canvas"></canvas> <script> // 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("Failure is success if we learn from it.", { backgroundColor: "#fffff0", width: 400, left: 110, top: 70, fill: "violet", strokeWidth: 2, stroke: "blue", textAlign: "center", transparentCorners: false, }); // Add it to the canvas canvas.add(textbox); </script> </body> </html>
Example 2
Passing transparentCorners as key with a "true" value
In this example, we are passing the transparentCorners property a true value. This will make sure that the controlling corners are rendered as transparent. Note that this is also the default behaviour.
<!DOCTYPE html> <html> <head> <!-- Adding the Fabric JS Library--> <script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/510/fabric.min.js"></script> </head> <body> <h2>Passing transparentCorners as key with a "true" value</h2> <p>You can select the textbox to see that the controlling corners are transparent</p> <canvas id="canvas"></canvas> <script> // 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("Failure is success if we learn from it.", { backgroundColor: "#fffff0", width: 400, left: 110, top: 70, fill: "violet", strokeWidth: 2, stroke: "blue", textAlign: "center", transparentCorners: true, }); // Add it to the canvas canvas.add(textbox); </script> </body> </html>
