Hi there what is this part doing a=w*!x. ? :)
u/BalintCsala

@alien I think that gets the image data at the current position and if it's red, makes the fillStyle black and vice-versa
u/nabbydude

@alien @BalintCsala is right, x.blahblah is 0 if the pixel is black and 255 if its red, inverting it makes 0 into 1 and 255 into 0, and then we multiply by w because its a big number (>255) to make the color more visible

safer for editing #webgl

u/IV

manga's original is grand, this is safer than my previous attempt in terms of editing and not getting errors which cause a reload :)
u/IV

the prblem with this is that youd have to clear both contexts which costs more bytes
