I want to test some things in AS3, and am currently trying to use some things i found on the internet. A lot of the examples are made for flex (i think)… they just dont work.  
Take for example the [pngencoder](http://labs.adobe.com/svn/flashplatform/?/projects/corelib/trunk/src/actionscript3/com/adobe/images/PNGEncoder.as)from adobe. Copy pasting it obviously doesnt work, so could anyone explain how to change it?..

Cant wait to try out all these examples :azn:
