There are areas that I want to show with "pattern" (ordered) dithering, they get dithered in photoshop, cut out, and pasted on top of another instance of the same image that was diffusion-dithered. After that, if I notice pixels that I don't like or if I feel more lines are needed, new pixels are painted onto the image.
AFAIK, Photoshop uses this algorithm for arbitrary palette pattern dithering: https://patents.google.com/patent/US6606166
FYI: The patent expired two years ago.
