tModLoader Map Viewer

Purpose-built map viewing and analysis tool for tModLoader worlds and mod-enabled maps. It reads map data from files or in-memory structures and renders overlays that reflect biome, ore, dungeon, and mod-specific layers. The tool emphasizes conceptual data flow: a parser ingests the world map, a layer manager composes multiple overlays, and a renderer produces a navigable image. It supports coordinate queries, region statistics, and export of previews for documentation. Who benefits: developers validating map variants, QA engineers verifying biome distribution, and community contributors creating tutorials or diagrams. The unique value is decoupling visualization from the game runtime, enabling faster iteration, reproducible visuals, and batch processing via scripting hooks. Core features include input validation, multiple layer support, zoom and pan state, and base grid rendering for spatial context. Use cases include comparing map configurations, generating region summaries for release notes, and producing visuals for wikis and documentation. The tool centers on deterministic color mappings, metadata extraction, and export options that accompany each image.
