I’ve been quietly working on two Ruby libraries that are starting to click together in a really interesting way:
- libgd-gis — the GIS brain: maps, basemaps, lines, polygons
- ruby-libgd — the raster engine: pixels, alpha, image scaling, compositing
Over the last days I added:
- lines, polygons and basemap switching to libgd-gis (0.1.3)
- color_alpha and copy_resize to ruby-libgd (0.1.9)
And together, that combination suddenly gives Ruby something it never had before:
the ability to render the same GIS scene over different map styles, just like a real GIS engine.
