well floyd-steinberg was easy to implement

ohhh yeahhhh

let's see if i implement the other dithering modes tonight or if i just keep playing with this and doing no work

i'm cheating a little bit truncating 8 bits of color into 6 bits to make the LUT manageable, but since the point of the tool is to reduce colorspace anyway it shouldn't be much of a problem

YESSS yes yes LUTs to the rescue

i've made sliders automatically update the preview again

this version is now live at the previous link

i need to build a palette LUT on load.

if for every pixel in an image i do a comprehensive color distance check for every color in a palette, a 320x240 picture takes ~3000ms

if i cache the results of the closest palette color to each color and fetch those when available instead of calculating, it takes... ~3800ms

fixed some bugs (namely the one where a palette wouldn't load half the time) and detached the control feedback from the image processing to make moving sliders on long operations less painful at the tradeoff of not having immediate output preview

yesterday i don't think this dithering was taking a whole 3 seconds, so now i need to chase down optimizations

turns out maybe javascript isn't the best tool for doing pixel manipulation on any image bigger than 10x10

unfortunately now i should 🔌 ​ ​

AAHHHHH i love this tool already

O.K. here's a very early release. only Atkinson is implemented right now and only uploading a file to serve as palette. have fun

OHHHH BABY THAT'S A 16 COLOR ATKINSON

oohhhhhhh buddy we're getting there

The functionality you are looking has been kicked around in various ECMAScript proposals, however it does not appear to be coming anytime soon.

i bet if i had put #webgbcam behind a paywall i would've seen more purchases than i have seen likes/thanks about it. it seems people value money less than they value feedback

it's starting to look like a Gizmo. like a Doohickey
