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.
