Ernest Delgado is having fun experimenting with
canvas. He has posted on one of his tests which involved creating a photo-table-like system.
You can visit the demo that allows you to work with some photos and export them out. You can play with adding borders, show corners for rotation, all on the fly.
It is a rich example, and Ernest explained how he did it:
Implementing this in canvas presents two main challenges: drag & drop and performance. I tried several approaches to solving these problems, and ended up using a multilayer solution which renders only the active image on the top-most canvas layer. This allows us to have drag & drop without needing to redraw every image each time one of them is dragged.
Ernest has some other fun things that he is playing with, which I hope to feature soon.
