If you’ve ever wanted to draw on an image or add a caption or text to your image then this is the plugin for you. Best of all it allows you to add your caption, save it, display it, then go back and edit it in different layers and objects laid on top of your image.
It extracts the text from the annotations and displays them as selectable and stylable text just below.
You can hold shift as you draw rectangles to make them perfect squares, same with the ellipse tool and circles.

This is a plugin that uses the HTML5 canvas and FabricJS to allow you to add shapes and text on top of images and display those images.
