I've used most of the available tools. The problem in this case is Q specifically mentioned PixelKnot app which uses a very specific implementation of F5 algorithm. None of the standard steg tools decrypt the PK encoded pictures.
It really drove (drives) me crazy, which is one reason I stopped messing with it.
Take a look at this. I followed it with a self created PK image, with and without password, using openjdk and oraclejdk. Still no joy to decrypt.

This may be right up your alley?

I understand what needs to happen, just don't know how to make it happen.
Cheers.
