[flexcoders] Trying to apply scale9grid to an image loaded at runtime

[Tom Bray]

I need to be able to load an image, allow the user to specify the  
scale9grid values, and then scale the image.  I've tried a bunch of  
different things but either the scale9grid values aren't used or I get  
an invalid parameter exception.  Is it possible to do this?

Thanks,

Tom
