How to add image to fabric canvas?
I have done a jsfiddle that loads a jpg image on the canvas, by using the fabric.Image.fromURL() function and the 'mouse:down' event. Inside the mouse:down i check if the user clicks on an object or just on the canvas.
here is a snippet of the javascript:
var canvas = new fabric.Canvas('c');
canvas.backgroundColor = 'yellow';
fabric.Image.fromURL('http://fabricjs.com/assets/pug_small.jpg', function(myImg) {
//i create an extra var for to change some image properties
var img1 = myImg.set({ left: 0, top: 0 ,width:150,height:150});
canvas.add(img1);
});
canvas.on('mouse:down',function(event){
if(canvas.getActiveObject()){
alert(event.target);
}
})
but my example also works ok ,if i dont use the extra variable:
fabric.Image.fromURL('http://fabricjs.com/assets/pug_small.jpg', function(myImg) {
canvas.add(myImg);
});
if you need more fabric events you can take a look here : http://fabricjs.com/events/

Hope helps , good luck.
This code is working properly but you need to use fabric.js file. You also need to use fabric.js CDN file in your header.
Fabric.js CDN->
var canvas = new fabric.Canvas('drawarea');
var imgElement = document.getElementById('my-image');
var imgInstance = new fabric.Image(imgElement, {
left: 100,
top: 100,
angle: 0,
opacity: 0.75,
width:300,
height:300
});
canvas.add(imgInstance);
#my-image{display:none;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/fabric.js/1.7.22/fabric.min.js"></script>
<canvas width="800" height="800" id="drawarea" style="border: 1px solid red;float: right"> </canvas>
<img src="https://via.placeholder.com/300.png" id="my-image" width="500px" height="500px">
