Quick tutorial on how to create a “glow” effect for any image / shape in Clojure with Clisk.
The idea behind the glow effect is to do the following:
- Start with an image that has an alpha channel indicating which areas are transparent
- Extract the alpha channel to get the pure shape of the object
- Create a glow effect by applying a blur filter to the shape
- Superimpose the original object on top of the glow
