PixelArt Processing Nodes for ComfyUI

This repository provides two custom nodes for ComfyUI that allow for pixel art image processing, including quantization, upscaling, and downscaling while preserving pixelated details.

Nodes:

1. Pixel Art Quantization Node

  • Description: Converts any image into pixel art by reducing resolution and merging colors into a limited palette.
  • Outputs:
    • A pixelated version of the input image.
    • A color palette with the selected number of colors.

2. Pixel Art Scaling Node

  • Description: Scales pixel art images up or down while maintaining crisp edges. Supports nearest-neighbor and bicubic scaling methods.
  • Outputs:
    • A scaled version of the input image.

Usage

  1. Clone or download this repository.
  2. Copy the folder pixelart_processing into the custom_nodes directory of your ComfyUI installation.
  3. Restart ComfyUI.
  4. Find the new nodes under the Image/Processing category in ComfyUI.

Features

  • GPU-accelerated pixel art image processing.
  • Configurable color quantization.
  • Sharp edge preservation during scaling.
  • Output of color palettes for further processing.
