I am using ImageSnapshot like this... snap_image = ImageSnapshot.captureImage(txtContainer, 300, new PNGEncoder()); ResponseString = ImageSnapshot.encodeImageAsBase64(snap_image); txtContainer is a movieClip that contains some dynamically created objects and it has eventListeners for roll over, out and click. Those no longer work after the snapshot is taken even when I try to reapply the listeners. Any tips?

I should be able to use the base64 methods since I imported the swc which has them, it compiles telling me that it can find the signatures but I get the following runtime error, im using a path to the library like C:\work\myproject\libs\as3core and in that location there is the swc as3corelib.swc Class mx.utils::Base64Encoder could not be found. thanks for any help I’m trying to do this in flash using flash develop but publishing through adobe ide.

Thanks, Tony Hi Peter,

Thats a great example , but can we create the vice-verca of that means creating image from this binary data.
