Please kindly update for Cordova 3.x. Awesome plugin btw
1+
Have anyone tried to use Javascript filter like CamanJS to accomplish this?
@quanghoc Yes but with Cordova seems to be really slow (like 15 seconda to apply a filter)
@billmn I'm thinking about rewriting CamanJS in an async / non-blocking way. Current bad performance is mostly due to the WebObject. iPhone 5S took about 1-2 sec but still noticable. What I did was to resize the image before processing.
@quanghoc Have you seen this? https://github.com/meltingice/CamanJS/wiki/About-the-block-renderer
Benefits:
- Image rendering is asynchronous, which means page rendering is no longer blocked.
- Slower filters get a nice speed improvement due to (fake) render concurrency. Of course browser JS engines are event-based and single-threaded, but by splitting up the canvas into separate chunks, we give more control to the JS engine for managing operations.
Caman already use this but is really slow yet.
I think the only way to have good performance in image processing is to take advantage of GPU ... therefore need a plugin that allows native access to hardware
Before writing this I tried caman and js rendering. The speed and quality will always lack from native.

Agreed @DrewDahlman . I just tried it, and although its cool for the web it leaves a lot to be desired on the phone. So Drew, from one Dahl-man to another, what are your thoughts on updating this? eh? ;p
