Explanation of diffusion dither in Photoshop

[TheAzzam]

What is the diffusion algorithm for diffusion that is present in the Save for Web option in the Export section? Can I find documentation of it online? Is Floyd-Steinberg a similar/same algorithm?

Hi!

Does anyone have an answer on this? I am currently working in depth with this feature and would be very thankful for any information/documentation.

My guess is that this comes under the category of "trade secret". Adobe don't usually disclose such details.

I was thinking in a similar direction. Thanks!
