Fabric.js Image Left Property

The left property in Fabric.js is used to set or get the horizontal position of an image object relative to the canvas top-left corner. The left value is measured in pixels and can be a positive or negative integer.

Setting the left Property

To set the left property of an image object in Fabric.js, we can use the set method of the object and pass in the left value as a parameter. For example:

var canvas = new fabric.Canvas('canvas');
var img = new fabric.Image(document.getElementById('my-image'));

img.set('left', 50); // Sets the image's left position to 50 pixels
canvas.add(img);
Getting the left Property

To get the current left property value of an image object in Fabric.js, we can use the get method of the object and pass in the property name as a parameter. For example:

var leftPosition = myImg.get('left');
Changing the left Property

To change the left property of an image object in Fabric.js, we can use the set method of the object and pass in a new left value as a parameter. For example:

img.set('left', img.get('left') + 10); // Shifts the image 10 pixels to the right
canvas.renderAll(); // Render the canvas to reflect the changes
Conclusion

In conclusion, the left property is an essential property in Fabric.js that allows us to control the horizontal position of an image object. We can easily set, get, and change the value of the left property using Fabric.js APIs. By learning how to use this property, developers can create dynamic and interactive canvas applications.
