Javascript PixelArt generator

Powered by OpenCV JS

This is a repository containg a simple code to automatically generate nice looking pixelart.

It provides the features of automatic pixellation with edge enhance to outline the edges of the images nicely. It also supports recolouring of the image with color palettes.

FAQ

Why? Isn't just a resize of the image ?

No, because there is also a sharpening phase involved, otherwise the result would just look blurry instead

API

// requires opencv.js 
function pixellate(imgElement, pixelSize, colors)
- imgElement: HTML image element of the page
- pixelSize: number of pixels of the original image to merge. Can be a float or int, from 0 to min(img.width, img.height)
- colors: list of colors in this RGB format

API example

let example_palette = [[200,0,0], [0,200,0], [0,0,200]];
// add element to the page
let img = document.getElementById('img');

// create a canvas openCV object
let canvas = document.getElementById('canvas');

// call pixellate
// 10 is the pixel size
pixellate(img, canvas, 10, example_palette);
