Work-in-progress / development repo for an "OpenGFX v2". Or maybe that should be OpenGFX director's edition, refactored OpenGFX, or perhaps OpenGFX extra zoom or OpenGFX 32bpp. Or some combination of all of them.
Partly derived directly from OpenGFX, partly redrawn or revised from my original 32bpp sources.
Far better organised sprites. Extensive use of automated composite sprite generation. Drawn and coded with extra zoom levels in mind.
Requires git lfs for large file handling.
Run make_all.sh to build the output .grf files. This makes a bunch of intermediate files *_8bpp.png and things in pygen directories.
Requires a system which can run bash shell scripts, python3 with PIL, blend-modes, numpy and nmlc.
Files used by python are .png files, but those may be derived from other sources. Raw raw sprites variously drawn\generated in Paint.NET, Aseprite, Blender and more.
Currently, output are "newgrf" .grf files which can be loaded to replace sprites. Ultimately (hopefully) will generate base graphics set .grf files.
