Alpha Choker

Alpha Choker

2D Modifier - Crop an image using alpha

Crop the image n pixels inward in order to cut the edges accordingly to the alpha channel of the image. Note that you can do some kind of a border on the outward of the image by setting the Choke parameter in negative. Here is an example (the right part is alpha choked by a -8.52 px) :


  • Choke (Floating point number) : Choke of the alpha choker
  • Iterations (Positive Number) : Iterations of the alpha choker
  • Size (2D Relative Size) : Size of the alpha choker
