This is my Doom text generator. It generates Doom text. It has several built-in fonts, and it can read most Doom-ecosystem font formats from WADs or PK3s. It also supports ZDoom-like color translations for recoloring text.
You probably want to use it via its hosted form: https://c.eev.ee/doom-text-generator/
You are, of course, also free to grab the source code and run it locally, but note that due to browser restrictions, it will not run from a file:/// URL. You will need a tiny HTTP server, like the one that ships with Python, which can be run with python -m http.server (with an optional port).
Most of the included fonts are commercial works extracted from commercial products, and I do not have permission to use them beyond the general air of quietly-tolerated remix culture in the Doom community and the fact that vanilla Doom requires a level graphic. C'est la vie.
I originally wrote this in a single day as an advent calendar idea, so the original iteration (doom-font-to-montage.py) is a hot mess of Python and ImageMagick.
I later improved on this somewhat:
-
The frontend can now read WADs, PK3s, and most notably FON2s, so I can ship FON2s directly and skip montaging them.
-
I wrote a new Python parser (
doom-font-to-montage2.py) that sucks less and uses Pillow instead of shelling out to the most godawful ImageMagick incantations you've ever seen in your life. -
I guess I'm maintaining two versions of every parser now but that's fine.
It's still fairly simple and straightforward: parse, lay out text, blit a lot.
