E-paper image converter

How it works

1. Pick your panel's size and colors.
2. Upload a photo, then crop it and choose portrait or landscape.
3. The image is dithered with a tuned Atkinson algorithmand matched to your panel's palette.
4. Download a .h, .bin, .png or .bmp file ready for your firmware.
