Is there anything like this for Linux?

kevin_thibedeau• 10 years ago

netpbm, imagemagick, Gimp. Take your pick.

And you totally missed the point. Yes, you can probably use these tools to get the same result but the first two are not GUI tools and the third is a kitchen sink included behemoth of a program.

What Lobo_tuerto asked is: Is there a similar tool that does this one thing and does it well and in a friendly manner available for Linux based operating systems?

My answer is "I don't know.".

They implement Atkinson Dithering? I wasn't aware of that.

More info here: https://en.wikipedia.org/wiki/Dither#Algorithms

This particular one seems to look pretty good when the pixel size is relatively large, but would give an inferior result compared to some of the others listed above for higher dpi. Also, it's too bad he didn't just disclose the specific details of the algorithm.

A friend of mine ported this to client-side JS a while back:

I'm not sure I'd call Atkinson Dither "sophisticated" (the author does). In fact it's a mathematical error that happens to look very cool on certain material.

Sadly, the effect falls apart when scaled. You can craft a beautiful Atkinson dithered vibey image but you pretty much can't deliver it. Text it, put it on a web page, drop it into iMessage, Skype it -- nobody just delivers bits any more. It looks particularly awful when not at 100% zoom.

Also the page's comparisons to Photoshop are misleading because you can do a Atkinson dither in Photoshop by setting the "Dither" slider to 75%. You'll probably find it looks better at 87.5% which throws away 1/8 of the error instead versus his 1/4.

While I realize this violates the "if it's new to you..." rule, Atkinson dither has long since been strip-mined to the bone for blog posts and karma. Flickr did it as an April Fool's joke years ago. Frankly if there's a graphics tool that doesn't support it I'd be surprised.
