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.
left
PropertyTo 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);
left
PropertyTo 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');
left
PropertyTo 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
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.
