I don't think the resolution is the problem with images on e-readers, but the amount of grayscale levels is.
Dithering works brilliantly on these devices. I made a photo frame out of one of these by calling some imagemagick from golang.
- dh-g 3y agoNice result. I agree, dithering on these devices works really well. After this project I worked on displaying images of the sun from the NOAA satellite. Until I got dithering working displaying the image with just 4 levels of grey was was very lackluster.
- Qwertious 3y agoResolution is more important than grayscale for e-ink - not only are they two sides of the same coin for dithering, but e-ink renders far faster in black-and-white so with sufficient resolution you've got a snappier page turn.
