pixel-space-asset-toolkit 0.1.4

Deterministic pixel-art space asset utilities for starfields, asteroid tiles, sprite cleanup, galleries, and previews.

Pixel Space Asset Toolkit

Deterministic procedural tools for pixel-art sci-fi prototypes: starfields, hex asteroid tiles, transparent-background cleanup, preview sheets, and Godot import guidance.

This repo is intentionally more visual than the audit tools, but it still behaves like a production CLI: fixed seeds, manifests, tests, and repeatable outputs.

Install

python -m pip install -e .

When published:

python -m pip install pixel-space-asset-toolkit

Tools

• starfield: deterministic pixel starfield backgrounds.
• asteroid-hex: deterministic transparent hex asteroid tiles.
• strip-background: converts a flat corner-color background to alpha.
• preview: builds contact sheets for review.
• compare: compares two PNGs and writes a red-highlight diff image.
• compare-dir: compares PNG sets and writes matching diff images by relative path.
• compare-manifest: compares generated PNG sets through manifests and reports field drift.
