Have Image bind to bytearray rather than bitmapasset or bitmap

I have an object that stores the compressed ByteArray version of an image (jpg or png). I want to keep it that way as the bytearray is about 30x smaller than the Bitmap it creates. The problem I run into is when I want to bind an image to this byte array. I can't really bind it to bytearray, because it requires a BitmapAsset as a source. Is there a way I ca开发者_开发问答n load a BitmapAsset from a bytearray but still bind to the bytearray when a new image is available?

Ok, so looks like I may have misspoke about assigning a byte array to the source. It looks like this does work and binding to a bytearray will work.

     public var test:ByteArray;
