Dithering was used to display pictures on old screens with limited colors and GIF technology also uses dithering. App supports two types of dithering: - Floyd-Steinberg — the most popular error diffusion algorithm (and it is the default one). - Ordered — the same algorithm which was used in old matrix printers. You can set matrix size there and see the difference. Share your images in social media with #ditherapp hashtag! And mention @ditherapp user on Instagram.
