How to get the source code of an image using FabricJS?
In this tutorial, we are going to learn how to get the source of Image using FabricJS. We can create an Image object by creating an instance of fabric.Image. Since it is one of the basic elements of FabricJS, we can also easily customize it by applying properties like angle, opacity etc. In order to find the source of an Image, we use the getSrc method.
Syntax
getSrc(filtered: Boolean): String
Parameters
filtered − This parameter is a Boolean value which indicates whether the source is needed for svg or not.
Using the getSrc method
Example
In this example, we have used the getSrc method to obtain the original source of the image. It can be seen in the console that a String representation of the source of the image is returned.

<script>
// Initiate a canvas instance
var canvas = new fabric.Canvas("canvas");
canvas.setWidth(document.body.scrollWidth);
canvas.setHeight(250);
// Initiating the image element
var imageElement = document.getElementById("img1");
// Initiate an Image object
var image = new fabric.Image(imageElement, {
top: 50,
left: 110,
skewX: 15,
});
// Add it to the canvas
canvas.add(image);
// Using the getSrc method
console.log("The Source of the image is: ", image.getSrc(false));
</script>
</body>
</html>
Using the getSrc method along with fromURL method
Example
Let’s see a code example of the logged output when the getSrc method is used in conjunction with the fromURL method.
