Models used by Relight

Bubbles & effects

The Bubbles & effects tool of Enhance draws in your browser with the engines of the Speech Bubble Generator and the Effect Lines & Screentone Generator by MIYADAIKU (Oyasumi Game Dev), used with the author's permission.

Bundled fonts

FukiAntique and FukiAntiqueB are reduced subsets of GenEi Antique and BIZen Antique, both by Otamon, renamed as the licence requires, under the SIL Open Font License 1.1. The pictures you make with them are yours: the licence covers the fonts, not what you draw. The full licence text: LICENSE_fonts.txt.

Screentone and Lineart

The Screentone tool of Enhance follows the “Manga-Lite” method of ComfyUI-MangaScreen by ashukae: the ink lines are traced on our servers by the MangaLineExtraction model (Li et al., “Deep Extraction of Manga Structural Lines”, SIGGRAPH 2017), then the tones and screentone are laid in your browser by a port of ComfyUI-MangaScreen's code. The Lineart tool of Enhance uses the same line model.
