Sorry, but not now. I still have hope of making some money from this, since I'm not really aware of any HTML5 image editor which outclasses my app.
Even though it doesn't earn me anything right now, I am just a little hesitant to share all the details about how it works. A lot of the specific canvas techniques I had figure out myself, and I'd rather not share all my tricks for free right away.
I did want to share some of the techniques I used in the form of blog articles however. I wrote one already on how to connect a series of points to draw a smooth curve: http://yangcanvas.com/smoothcurves
Thanks! I obviously worked my ass off on this thing, and as many features as there are, there are still many more that I would like to add and tweak.
But I probably won't put more work into this code in the near future. So far it hasn't retained any regular returning users, and I don't want to invest any more of myself in this software if it is just going to collect dust.
Really nice work. A flash-like canvas animation is due gain popularity in the near future.
Your fill-bucket tool is a little freezy, as I'm sure you are aware. I made an HTML5 static image editor http://yangcanvas.com/paint and I found a good fill-bucket tool hard to implement too. Your tools does fill ranges perfectly, which is really nice. Good luck making that work more efficiently without sacrificing precision as I did.
