Function extract_primary_fonts 

pub fn extract_primary_fonts(
    chain_family: &FontFamily<FontFallbackChain>,
) -> FontFamily<FontData>

Extracts primary fonts from a fallback chain family.

This creates a FontFamily<FontData> from a FontFamily<FontFallbackChain> by taking the primary font from each chain. This is useful for compatibility with genpdfi which expects FontData rather than chains.

Arguments

• chain_family - The fallback chain family to extract primaries from

Returns

A FontFamily<FontData> containing the primary fonts
