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.
Download the ComfyUI-PixelDetector.py into custom_nodes folder.
Palette: If enabled, automatically reduces the image to predicted color palette. Max Colors: Max colors for computation, more = slower, default = 128
Thanks to @Astropulse and @paultron for the downscaling logic. I just wrapped it as is into a ComfyUI custom node. Big thanks to https://github.com/paultron for numpy-ifying the downscale calculation and making it tons faster.
