Floyd steinberg dithering演算法
Web1. I'm trying to implement Floyd Steinberg algorithm in Java, working with java.awt.image.BufferedImage. I've used the algorithm described here with a custom palette, and I was expecting to get more or less the same image as in the wikipedia example (or as generated by Gimp for example), but I get a very different version. You can see what I get.
