    What is the algorithm for Outer Glow "Softer"?

    VinnieFalco

      I'm trying to implement some effects in C++ for my user interface controls. I've figured out that Photoshop Layer Styles uses an anti-aliased form of the Euclidean Distance Transform for "Precise" techniques (Inner Glow and Outer Glow).

       

      But what is the method used for the "Softer" technique for Outer Glow and Inner Glow? It seems this is also used for the "Smooth" technique when computing the height map for Bevel and Emboss.

       

      Any pointers would be appreciated!
