I've been playing around with inkscape today and created a few transparent icons and I want to make them not only transparent, but also to give them the blur the other objects (window titles, transparent windows) have thanks to compiz. I've tried setting it up a bit but I think I'm missing the "blur-depth" bitmaps for my icons which is not a problem, I can create them but I have no idea how to link them with the icons on my desktop. Could someone tell me how do I assign such "blur-depth" bitmaps to the icons I've created ?
I have no experience in making themes or graphics for compiz whatsoever so I appreciate any help.

Thanks Joey
