   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

     OK here is a first release!!!

     https://maple.pet/ditherinator #ditherinator

     i gave up for now on quantizing colors from the source image bc it's harder than i thought, but you can still upload your own palette PNGs and use the built-in ones

     HAVE FUN AND SHOW ME COOL PICTURES

     OK OK i finally implemented bayer

     if i can get some work done on palettes (add built-ins, sampling from image) i'm properly releasing an initial version

     fedel repeated this.

     here's a cool little picture in 640x480 with only the 16 EGA colors. you could set this as your windows 95 wallpaper

     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

     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
