Public Member Functions
std::pair< double, double >	normalizedFontStretchRange () const
	Return ordered, inclusive width percentages. Invalid programmatic ranges (negative or non-finite endpoints) fall back to fontStretch. Zero is canonicalized to positive zero.
std::pair< int, int >	normalizedFontWeightRange () const
	Return ordered, inclusive endpoints. Programmatic endpoints are clamped to 1-1000; parsed out-of-range descriptors are rejected before constructing a face.

Static Public Member Functions
static double	FontStretchPercentage (int stretch)
	Convert a legacy named width to its CSS percentage: normal (5) becomes 100.0.

Public Attributes
RcString	familyName
	font-family descriptor
std::vector< FontFaceSource >	sources
	ordered src list
int	fontWeight = 400
	First weight endpoint (integer 1-1000, 400=normal, 700=bold).
int	fontStyle = 0
	font-style descriptor (0=normal, 1=italic, 2=oblique)
int	fontStretch = 5
	font-stretch descriptor (1-9, 5=normal, matching FontStretch enum) Optional second weight endpoint. Absence means the scalar fontWeight value.
std::optional< int >	fontWeightMaximum
std::optional< std::pair< double, double > >	fontStretchPercentRange
	Optional width endpoints in percent (100 means normal), overriding fontStretch when valid. A single percentage uses equal endpoints; absence preserves the legacy named-width field.

Detailed Description

In-memory representation of a single @font-face rule.

FontFaceIdentityKey covers every effective descriptor and source below. As explained for FontFaceSource, extend the key with any field added here; otherwise two rules differing only in the new field become one and the second is dropped.

Member Function Documentation

FontStretchPercentage()

double donner::css::FontFace::FontStretchPercentage ( int stretch )

static

Convert a legacy named width to its CSS percentage: normal (5) becomes 100.0.

Parameters

stretch

Named-width ordinal, clamped to 1 (ultra-condensed) through 9 (ultra-expanded).

Returns

The corresponding percentage, from 50.0 through 200.0.
