Both command-line tools are open source (MIT licensed) and built with .NET 10. Prebuilt binaries are available for Linux, macOS, and Windows.
Currently only orthographic maps are supported, and there may also be limitations or bugs I haven’t discovered yet.
I’m still working on improving them when I have time and feel like it, so if you try them out, I’d really appreciate any feedback, bug reports or contributions.
That could definitely be useful to somebody, thanks for posting them!
It does seem like functionality that would be nicer to support in Tiled itself, where it could re-use all the existing code for parsing and rendering maps, as well as being more readily available to users. Since Tiled 1.11, tmxrasterizer can already export multiple frames, it’s just lacking the option to immediately turn it into a GIF (though this also gives users the flexibility to use any other animated format).
Being able to open an image as a tile map, where a tileset gets automatically extracted, would also be a nice feature to have in Tiled.
