excellent information ^^^. i also have been diving deep into canvas-based image fiddling lately and you covered most of the good bits. the only thing i'd add is maybe look into the `ndarray` library: https://github.com/scijs/ndarray https://github.com/scijs/ndarray for efficient manipulation of multidimensional arrays. this could help slice and dice by channel, or crop, flip, rotate, et cetera. that plus convolution and other fun stuff.
