[22:19:07] <PSvils> hey guys!
[22:19:25] <PSvils> I was wondering if nme.display.BitmapData.setPixel() works fast in the Javascript target?
[22:19:34] <PSvils> (comparable with the Flash target in terms of performance?)
[22:19:49] <_discovery> why not try it ;)
[22:20:20] <PSvils> don't have everything ported over to it etc., but true say.
[22:20:39] <PSvils> then again, I've become afraid of the HTML5 NME target since it's buggy as hell.
[22:21:31] <_discovery> i meant just an isolated case, do a setPixel every frame on a large image/size and a small size
[22:21:40] <_discovery> and compare the same to cpp, cpp will be dead slow often
[22:21:51] <PSvils> oh yeah, cpp will die from it for sure.
[22:21:52] <_discovery> so you should be able to tell immediately BUT
[22:22:00] <PSvils> I just wanted to compare HTML5 vs. Flash though.
[22:22:12] <_discovery> most cases it will be 'ok' , i mean lots of set pixel stuff for html5, its kinda case specific
[22:22:33] <PSvils> case specific? but my case is doing lots of setPixel operations in HTML5? :D
[22:22:36] <_discovery> what i mean is : html5 in general, has images as arrays of color you can manipulate
[22:22:44] <_discovery> and its not slow at all, depending on the operations
[22:23:08] <PSvils> ah, well...replacing values then should be pretty quick no?
[22:23:08] <_discovery> let me find an example i saw
[22:23:12] <PSvils> sure!
[22:23:14] <PSvils> :)
[22:25:02] <_discovery> so
[22:25:03] <_discovery> http://www.html5rocks.com/en/tutorials/canvas/imagefilters/
[22:25:05] <_discovery> these examples
[22:25:15] <_discovery> the more 'heavy ones' will not work well at all in realtime right
[22:25:37] <_discovery> but you could get away with for example, downscaling the image and blurring a smaller version and then blending it on top for bloom effect
[22:25:49] <_discovery> its case specific because lots of tricks can be applied at many levels
[22:26:04] <_discovery> and set pixel is not necessarily slow in flash/html5 but it CAN be
[22:47:34] <PSvils> aha, gotcha :)
