JS Transform Handles
9 years ago
The other day I was playing around with Mozilla’s Popcorn Maker and I had the idea of using HTML/JS/CSS to create transformable divs using transform handles and a bounding box. I did a quick search for any existing examples of HTML transform handles but i couldn’t find anything so I decided to give it a go myself. Below is a demo of what I came up with. It might not be the best solution but it works pretty well. I even implemented rotation but I had some issues with the scaling when the element was rotated. The demo has the rotation disabled but you can get the source by view the source of the frame. All JS, and CSS is in the one HTML file. Enabling the rotation is as simple as removing display none from the rotation handles CSS style.
The main reason I wanted to create transformable DIVs is for the next version of my Module Builder. I had experimented with transforming HTML via the AIR app but I think doing it directly in the HTML page.
