Pixel Detector

Downscale and restore pixel art images that have been resized or corrupted.

This is primarily created to fix compression issues from saving pixel art in jpg format.

Built into Aseprite with Retro Diffusion pixel art generator (Edit -> FX -> Repair pixel art): https://astropulse.gumroad.com/l/RetroDiffusion

Exaggerated example:

Usage

Arguments:

-i --input: Expects string, Path to input image

-o --output: Expects string, Path to save output image, default = output.png

-m --max: Expects int, Max colors for computation, more = slower, default = 128

-p --palette: Expects none, Automatically reduce the image to predicted color palette
