resolve_font_file

fn def resolve_font_file(family: String, slant: FontSlant = FontSlant.NORMAL, weight: FontWeight = FontWeight.NORMAL) -> String

Resolve family/slant/weight to an absolute font file path.

Generic and metric aliases are expanded, and an unrecognized family falls back through the default sans list, so this raises only on a machine with no installed fonts.

Scans the font directories on every call; build one FontDatabase (or FontCache) to resolve more than a handful of fonts.

Args:

• family (String): Font family name or generic alias (e.g. “sans-serif”).
• slant (FontSlant): Requested upright/italic/oblique style.
• weight (FontWeight): Requested normal/bold weight.

Returns:

String: The matched font’s absolute file path.

Raises:

Error: no font files were found on this machine.
