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
Clone or download this repository.
Copy the folder pixelart_processing into the custom_nodes directory of your ComfyUI installation.
Restart ComfyUI.
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.
