Fixes AI-generated pixel art using strategies like majority and average color sampling
What is Fixelart? Features and use cases explained.
About Fixelart
fixelart is a TypeScript library that cleans up AI-generated pixel art by intelligently downscaling and recoloring blocks using various mathematical strategies. Install it via npm (npm install fixelart), provide an RGBA pixel buffer, choose a strategy (e.g., majority, average, geometric mean), and optionally adjust tolerance or shrink output. The library returns a fixed pixel art image, ideal for game developers who need to polish AI-generated sprites or tiles.
Use Cases
- ▸Clean up AI-generated character sprites before importing into a game engine like Unity or Godot.
- ▸Fix blurry tileset textures produced by text-to-image models for use in 2D retro-style games.
- ▸Batch-process multiple AI-generated pixel art assets to apply consistent artifact removal across a game project.
Features
- ✓Provides multiple strategies for fixing pixel art, including majority, average, geometric, harmonic, and quadratic means.
- ✓Allows configuring color tolerance to control which pixel values are considered equal during processing.
- ✓Offers an option to shrink the output so that each output pixel corresponds exactly to one logical pixel.
- ✓Integrates easily with existing TypeScript or JavaScript projects via a simple function call (`fixImage`).
FAQ
Does fixelart work on pixel art that wasn't generated by AI?▼
Yes, fixelart can be used on any pixel art image, but it's specifically designed to remove color bleeding and blurring artifacts common in AI-generated pixel art.
Can I process multiple images at once?▼
fixelart is a library, so you can write a script to loop through multiple images and call `fixImage` for each one. Batch processing is straightforward.
What image formats does fixelart support?▼
fixelart works with raw RGBA pixel data, so it can accept input from any image format (PNG, JPG, etc.) as long as you decode it to RGBA first. The example in the README uses `pngjs` for PNG files.
