<p>

Load an image, click Go and wait (potentially for a while) for the image
|
||
|
|
to be dithered using the Nord color palette and the Floyd-Steinberg
|
||
|
|
algorithm.

Running in the browser with Wasm causes a bit of a performance penalty.
|
||
|
|
Multithreading is not available (not that it matters much since
|
||
|
|
Floyd-Steinberg is single-threaded), and sending data back and forth
|
||
|
|
between JS and Wasm can take a little while.

I've re-used code from

to make the Wasm code run in a web worker, with some adaptations for Go
|
||
|

oddities.

If you're into that sort of thing, source code is available on
