Detailed Description

Decompress a WOFF2 font file into a raw TTF/OTF byte stream.

WOFF2 fonts use Brotli compression and a custom table transform to achieve higher compression ratios than WOFF 1.0. This parser delegates to the Google woff2 library (decode-only) to reconstruct the sfnt byte stream.

See also

https://www.w3.org/TR/WOFF2/ for the WOFF2 specification.

ParseResult< std::vector< uint8_t > > donner::fonts::Woff2Parser::Decompress ( std::span< const uint8_t > woff2Data )

static

Decompress WOFF2 data into a flat TTF/OTF byte stream.

Parameters

woff2Data

The WOFF2 file data as a byte span.

Returns

A ParseResult containing the decompressed sfnt bytes on success, or a ParseDiagnostic on failure.
