Diffuse is very similar to Adobe Photoshop’s own diffuse filter with a key difference – it supports sub-pixel (fractional) diffusion. This key feature takes the diffusion effect to a whole new level and now makes it useful for production where antialiasing effects are necessary.


Adobe Photoshop’s integer-based diffusion algorithm produces harsh aliasing seldom useful for any kind of professional work. By using sub-pixel diffusion, the results are subtle and fully integrated within the image. Applying several iterations of the effects at one time produces even more pleasing results.


Sub-pixel diffusion means you can apply diffusion values less that 1.0 pixel.


Diffuse is 100% multi-threaded capable of using an unlimited number of cores for ultimate speed.


Amount: Controls the maximum amount of diffusion (distance of pixels / 100.0). For instance, a value of 100 will diffuse pixels up to 1.0 pixel in any direction.

Iterations: Controls the number if times the diffusion is applied. For instance, if you apply 400 diffusion with 20 iterations, your image will be diffused at a rate of 400, 20 times over. Increasing the iterations produces a ‘frosted glass’ type of effect.


Seed: Changes the random generator seed.
