Seems really laggy to me, Fx3.6.12/mac Great idea though. How do you do the edge detection? Sounds like a neat feature.

- leif 16y agoLaggy here too. Same FF build, on ubuntu. Fast in chromium. Sidenote, does anyone know of a good JS profiler? Edge detection is easy, especially on images with small numbers of colors in large swaths.
- showerst 16y agoI've found firebug's profiler to be quite useful: http://michaelsync.net/2007/09/10/firebug-tutorial-logging-profiling-and-commandline-part-ii http://michaelsync.net/2007/09/10/firebug-tutorial-logging-p...
- magichacker 16y agohi, u r right - not really performant in FF, developed/tested it on chrome, safari and iPad safari (which my kids love, it's mostly coded for them) so far .. will look into FF and make some performance enhancements.

- magichacker 16y agoi commented out a console.log(touch.pageX); and now the performance in FF seems to be much more smoother? can it be? it did not even get executed? strange.
- leif 16y agoIt's now fast for a few seconds, then gets slow shortly after the footer loads.
- magichacker 16y agoafter a long hard fight i made it faster (overall but especially in FF) .... the CanvasPixelArray Object (which is not an Array in Webkit ....) is a real bastard.
- magichacker 16y agohi, i started of here http://developer.apple.com/safaridemos/CanvasPixelManipulation/ http://developer.apple.com/safaridemos/CanvasPixelManipulati... (look into the sourecode) but tuned the internal edge detection parameters to work better with children book covers. said that, i came across a lot of ... potential within these algorithms to make them way cooler. will probably work on them during another rainy weekend.
