A gem to convert a picture into black and white grid

Question

I have to convert a colored picture into a duotone black and white picture. I forced the edges to have good result, but the result isn't good enough.

I'm using rMagick with Ruby, but I'm looking for a better gem.

What do you mean with "I forced the edges to have good result, but the result isn't good enough." example of desired picture and what you got? — mb21, Jan 29 '16 at 09:03
It probably a question of finding the right parameters, and not one of finding another gem. — Meier, Jan 29 '16 at 13:04
It's about the way to get a duotone picture efficiently enough to be able to get pixel by pixel a grid of the game "nonogram", "logigram" or "picross". — Jérémy JOKE, Jan 29 '16 at 18:03

Paperclip is really great. You can use different processors and make with your pictures nearly everything.
