> Note that this is a resource-intensive filter. Memoization is strongly advised!
Can you make this be the default for non Safari browsers? This really made my CPU fan work hard. Also, why does this need to recalculate the image so many times a second if it is the same image each time? It really only needs to redraw when I change one of the options.
The demo is a part of the testing regime for my canvas library. I set the default to "don't memoize" because it's the quickest way to see how intense/computationally expensive the filter gets using different parameters. For most scenarios the output should be memoized (to stop unresponsive websites, device damage, etc)
My ultimate goal would be to get the filter working more efficiently on dynamic input eg a video media stream. So far only the simplest settings (2 colours with dither) are watchable: https://codepen.io/kaliedarik/pen/OJOaOZz
