Adding and Transforming Images
index.html
To display an image on a Fabric.js canvas, you use the fabric.Image.fromURL method. This function loads an image from a provided URL and creates a Fabric.js image object. Once the image loads, you can set properties such as position, rotation, and scale before adding it to the canvas.
The process begins by initializing the canvas using new fabric.Canvas('canvas-id'). You then call fabric.Image.fromURL, passing the image URL and a callback function. Inside the callback, the loaded image object is available. You can call set on this object to adjust properties like left and top for positioning, angle for rotation, and scaleX/scaleY for resizing. After customizing these properties, you add the image to the canvas with canvas.add(imageObject). Activating the image with canvas.setActiveObject(imageObject) allows users to interact with it—such as moving, scaling, or rotating—using the built-in Fabric.js controls.
