Hi,

I want to let a user upload a PNG-file with alpha transparency and have it compiled by the server to a swf-file with jpeg compression on the embedded PNG-file.

How can I make this happen?

I thought first I’d just construct a class and compile it with Flex Framework, but Flex does not compress the embedded PNG-files. You who have tried have probably ended up making an assets.swf file compiled from within the Flash IDE.

Any thoughts appreciated.

Kind regards,
