OutlineCheck

OutlineCheck is a Python-based tool for analyzing and fixing bad outlines in pixel art sprites.

It detects common outline issues such as staircase effects, jaggies, and broken outlines, then applies automatic corrections to improve visual consistency and readability.

Features

• Automatic outline analysis
• Detection of staircase outlines
• Detection of jaggies and broken outlines
• Smart outline correction
• Designed for pixel art sprites
• Useful for artists and game developers

How It Works

OutlineCheck scans sprite contours pixel by pixel to identify outline patterns that break pixel art rules.
Detected errors are corrected using simple and consistent outline logic.

Goal

The goal of OutlineCheck is to save time and improve sprite quality by automating outline cleanup.
