Hello,

I'm trying to make a paper cut-out effect around object. So I need begin with "expanding alpha" channel to bloat the object and then fill with paper texture behind.
However since my images are rather large, SimplChoker at it's max (-20) is giving very modest expantion. Is there other filter which I can use for same purpose ? Stroke would fit well, however it doesn't work with alpha - only with masks. Any other ideas ?

Thanks, M.

Effect --> Channel --> Minimax
Effect --> Matte --> Matte Choker

+ any kind of blur followed by Levels adjustments.
