KnockOut is just that

Corel (Ultimatte) KnockOut is a great tool. I have worked with Mask Pro, Magic Mask, and many other tools. The old Ultimatte slogan was "there are no edges, only transistions" is right on. This tool does a beautiful job that the built in stuff in Adobe does not handle. The $99 is worth the time saved and the quality of the images.
