Srijika Uses Latent Diffusion to Restyle Fonts Across Nine Indic Scripts While Preserving OpenType Layout

loopdesk-ai · hf · 2026-09-18

Srijika is a system for producing installable OpenType fonts for nine Brahmic scripts (Devanagari, Tamil, Bengali, Telugu, Kannada, Malayalam, Gujarati, Gurmukhi, Odia).

Instead of generating fonts from scratch, it restyles glyph outlines from shaping-complete template fonts, preserving cmap, GSUB closure, and GPOS data—solving the core Indic challenge of keeping hundreds to thousands of conjuncts, half forms, and matra variants consistent under OpenType shaping.
It outputs 66 TTFs (57 curated presets plus nine open-vocabulary showcase fonts), all passing OpenType Sanitizer, with HarfBuzz and CoreText reproducing template glyph-ID sequences; a full-closure audit covers 80,915 glyphs and 54,812 anchors.
Style selection uses Lipika, a retrieval index over 650 open-license font families; a reference-conditioned latent diffusion model redraws glyphs, followed by content gating, harmonization, and shaped-cluster verification.
The report includes a negative-results catalogue: on held-out SSIM gates, template copying beats generation on 50 of 56 faces, and the authors urge caution interpreting style-movement metrics.
