Displace away from Matte? (like iDisplace in shake but outward )

[Hugh]

Sounds like you want a DilateErode (in Shake)....

Can also be done just by blurring and adjusting the contrast (only works on a matte, though - will lose quality in any image you push through it)

Sorry If I was a bit unclear.

I don't need to increase the size of the matte, I need a way to use a matte in the same way you would use a matte for an iDisplace but instead of moving +/- x and y in one direction it would move a certain amount in a direction determined by the shape of the matte itself.

Think of a clock, if you had a white circle on a black matte, in the area of 3 o'clock the image would be displaced (5, 0), at 9 o'clock (-5,0), at 1:30 (2.5, 2.5) etc. (I know the 2.5 bit isn't mathematically correct but you get the idea)

Right now Im using two embosses to get two mates, a top right displace matte and a lower left one, each is kind of like half of an edge detect. I am then bluring them and putting them into two iDisplaces the push in opposite directions. It kind of works but it doesn't really warp very evenly.

What Im really looking for is a spherarize type effect that follows the shape of a matte instead of a circle.

Thanks,
Casey
