Flash image upload with mandatory crop?

问题:

Anyone know of a Flash file (image) uploader that will force a user to resize and/or crop their image BEFORE uploading it? To then upload it as well.

Basically, I don't want my server processing the image resize/crop. I want to specify a target aspect ratio and have the user resize and crop their image to make it fit.

I've seen cropping uploaders before but they all seem to be server side. I saw a Flex one but I'm not sure it's "mandatory" -- Basically if the user just uploads the image without making edits, then I'd like the Flash to scale and fit the image into set dimensions...Leaving it I guess short in one direction to not stretch.

Anything like this out there? Thanks!

I have a bounty running with a very similar question, be sure to take a peek - there isn't anything there yet that does client side resizing, though.

Also, SWFUpload is said to support it in the new Beta, but the feature is very sparsely documented right now. You would probably have to work on it to get it running the way you want.

there was another one called resize before upload but the site went down. though while I'm updating this and we're on the subject -- I don't see why you'd want to use Flash these days for this task. There are plenty of JavaScript options and now we also have Google's Dart (which builds JavaScript).
