This is how we did it—using multiple graphic objects stacked. However, I used a gradient for each edge and used Outer Glow. I think it would be a lot of work to script this for general work but Brahmanathaswami seems to think it will be worthwhile to try it. I'm interested to see what he comes up with.

When I set the blending ink to BlendScreen, the black graphic became completely transparent, regardless of the inner glow settings. FWIW, I was able to easily create a feathered image for an oval or circular feather with one graphic object. To do it for a rectangle, took 4 graphic objects. In each case, we used Outer Glow with a gradient—radial for the oval, linear for the rectangle. > Regards, > > Scott Rossi > Creative Director > Tactile Media, UX/UI Design > > > > > On 2/3/16, 7:38 PM, "use-livecode on behalf of Howard Bornstein" > <use-livecode-boun...@lists.runrev.com on behalf of > bornst...@designeq.com> wrote: > > >Yes this is true and understood.
