I talk about facts. You can review my posts in this thread. I will resume them to you to make things easier:

- ebooks use color images because their primary target isn't just e-ink devices
- color images don't match the e-ink palette, so they're prone to color banding artifacts (as the first image in the link I gave you)
- dithering is applied to images to prevent these artifacts.
- on device dithering (HW or SW) doesn't produce better results than preprocessing images with an specialized software, like ImageMagick, but it is way better than original images.

I know it could be harsh for you to understand that because you have some sort of magical belief but dithering doesn't afect the resolution of an image..

If you see a pixelated image that's not because of dithering. It is a match of a low quality image paired with a css rule that enlarges the image, making its low resolution more obvious.

But you don't care about facts and I don't care about insults. So please believe what you want. I'm out.
