mcmap

What mcmap is

mcmap turns Minecraft save files into isometric pixel-art maps. It reads saves from the standard folders on Linux, macOS and Windows, then creates a PNG by default; an option splits maps into square image tiles. Rendering controls include circular or coordinate-bounded areas, dimension selection, shading, lighting, water and beacon toggles, and map direction. A JSON color file lets users change block colors and rendering types. The renderer processes terrain in batches using all computer threads. Rendering a whole map at once may require 10+ GB of RAM, and a fragment-size setting can manage batch sizes. The project is used from a terminal or PowerShell, with an experimental GUI for Windows. Its v3.0.0 release specifies support for Minecraft 1.13+. mcmap is free and open source under GPL-3.0, with precompiled binaries and source code available. Building it uses CMake and requires zlib, PNG, fmt and spdlog. The project notes that merging batches can leave visible lines in oceans; changing fragment size or water settings may address that issue.
