resvglite
A thin PyO3 binding of resvg — the optional, self-contained SVG rasterizer behind saitenka's inline dictionary glyphs (issue #283).
Yomitan structured-content dictionaries embed inline img nodes that are almost always SVG gaiji
(外字) — sense/section markers, orthography labels, reference glyphs (参照 / 表記 / 一). Pillow cannot
rasterize SVG, so saitenka drew each as a ▢ box. resvglite rasterizes an SVG to a PNG at import; the
renderer composites and tints it.
API
import resvglite
png_bytes, width, height = resvglite.render_svg(svg_bytes, size_px=64)
render_svg(data, size_px) rasterizes data (SVG bytes) to a PNG size_px tall, aspect-preserved,
returning (png, w, h). Raises ValueError on invalid or zero-size SVG.
Why a vendored binding
resvg is pure Rust (usvg parser + tiny-skia raster) — no system libraries (unlike cairosvg/pyvips),
so it ships prebuilt wheels: three per platform (pyo3 abi3 + abi3t, PEP 803) — abi3 (GIL 3.13+), cp314t
(free-threaded 3.14), abi3t (FT and GIL 3.15+, gil_used = false), the same self-contained-wheel bar
as taffylite. It is an optional add-on: without it, saitenka falls back to the
▢/label placeholder.
Licensing
resvglite itself is MIT OR Apache-2.0. It vendors resvg/usvg/tiny-skia, which are MPL-2.0 (a
file-level weak copyleft): the MPL covers only those vendored source files, not this wrapper or any
code that merely imports it. Because resvglite is a separately published, optional wheel, that
copyleft stays contained to this package — the core saitenka dependency graph remains permissive. See
NOTICE.
