Is there a simple open web image editor? I know about Pixlr, Picnik, and Aviary, but those all use Flash. It seems like it should be possible to make one using Canvas and other modern open web technologies.
In addition to using it for simple photo manipulations, I'd like one that can be embedded into other applications, like Personas (to make it easy for users to make and refine their own personas) and image hosting sites (so users don't have to go to a separate website and import their images to edit them).
In other words, I want the web-based image editing equivalent of Gecko+Firefox: a great open-source image rendering and editing engine with a flagship product that demonstrates its capabilities and an API for embedding it into other applications.
Is there such a thing? Does anyone want to create one?
