After my last post about image resize using flash I did some research and found this:
I tried to get it to work and saving the crop server side.
I manage to get to work pretty easy on my local server but after uploading it the php was giving me trouble.
So I stripped it down and now its working great: flash resize and crop
If you want the source: download
About flash client side resize, no luck.
I found several Java ones and also I know that is possible to do it in flash but the methods I found were to explode the image pixel by pixel and then pass it like that into php. From what I could understand quality problems and flash player frozes on large images were the problems using that option.
Anyway. I think this was a great step foward.
