You can do many of these effects in plain CSS using the filter operator. As a bonus, you get hardware acceleration if you combine them with translate3d(0, 0, 0).
That is true, but grafi.js relies on a browser's canvas API to convert an image to a Uint8ClampedArray of colour values, so it won't work on a command line or backend either. As a way to learn about convolution filters it seems fairly good though.
Good point. https://www.npmjs.com/package/get-pixels can help parse an image to pixels, but it returns a different format than the canvas API's Uint8ClampedArray.
that is wrong way to do this - write efficient code (simple operations on an array) instead of using huge canvas library to make a library you don't need to use usable
What I thought was really cool about this though, is that I can start making a "mini-photoshop". It wouldn't be very efficient at all, but I think you could find a way to mix effects together on parts of the picture selected by the user which is what a mini-photoshop is to me. Or maybe I should just look into canvas, but at least I have the choice now.
And even if I programmatically insert inline CSS, there's always the compatibility issues and filter restrictions.
