Re: Convert photos to Atkinson dithering

This implementation is great and the interface brings back memories. I was wondering why my Atkinson dithering web-component[0] was getting more hits today - sad news. I’ve always thought that Atkinson dithering produces the nicest images on really crisp monitors like the original Mac - something about it just looks cool and 80s which is why I used it in a game last year.

Woah cool web component!

Interesting that one of the size options is 512x384, not 512x342 which was the original mac resolution.

The very first Mac really was 512x342 [0]

Edit: Sorry - I misread what you were saying and intended this as a correction, but you had it right all along.

Don't click the "as follows" in the info dialog. Looks like this wasn't updated in a while and since then the link became NSFW.

There's no guarantee that the site's creator is (or becomes) aware of this thread, so when possibly it's nice to give them a heads-up! I have just done so: https://github.com/gazs/canvas-atkinson-dither/issues/2

Earlier quoted context omitted.

In his defence, that attribute has been available in browsers since March 2017 according to your link [1], whereas the most recent commit in the repo for the dithering tool was in March 2016 by the looks of it. https://github.com/gazs/canvas-atkinson-dither He’s still active on GitHub though, in other repos. Maybe he will accept a pull request? :) [1]: https://developer.mozilla.org/en-US/docs/Web/API/HTMLAnchorE...

Oh, I assumed it had been recently built and probably posted today by its author given the news and the lack of a year in the title. I'll open a PR. edit: I might open a PR. 'CoffeeScript...now there's a name I've not heard in a long time. A long time...'

CoffeScript? This is the kind of task where a coding agent should be helpful.

Is it the same Atkinson that died today and is this a tribute ?

In a sense, but the first commit in the repository was 15 years ago - it's not something that someone whipped up in response to the news.

I adore dither as a tool for my designs. Kudos to Atkinson and everyone involved in the introduction of these algos. They mean a whole world of childhood to me, and a lot more.

p.s. dithermark.com is super cool also.
