Implementations

impl FontInfo

pub fn from_source(source: SourceInfo, index: u32) -> Option<Self>

Creates a new font object from the given source and index.

pub fn source(&self) -> &SourceInfo

Returns an object describing how to locate the data containing this font.

pub fn index(&self) -> u32

Returns the index of the font in a collection.

pub fn load(&self, source_cache: Option<&mut SourceCache>) -> Option<Blob<u8>>

Attempts to load the font, optionally from a source cache.

pub fn width(&self) -> FontWidth

Returns the visual width of the font– a relative change from the normal aspect ratio, typically in the range 0.5 to 2.0.

pub fn style(&self) -> FontStyle

Returns the visual style or ‘slope’ of the font.

pub fn weight(&self) -> FontWeight

Returns the visual weight class of the font, typically on a scale from 1.0 to 1000.0.

pub fn synthesis( &self, width: FontWidth, style: FontStyle, weight: FontWeight, ) -> Synthesis

Returns synthesis suggestions for this font with the given attributes.

pub fn axes(&self) -> &[AxisInfo]

Returns the variation axes for the font.

pub fn has_weight_axis(&self) -> bool

Returns true if the font has a wght axis.

This is a quicker check than scanning the axes.

Returns true if the font has a wdth axis.

This is a quicker check than scanning the axes.

pub fn has_slant_axis(&self) -> bool

Returns true if the font has a slnt axis.

This is a quicker check than scanning the axes.

pub fn has_italic_axis(&self) -> bool

Returns true if the font has an ital axis.

This is a quicker check than scanning the axes.

pub fn has_optical_size_axis(&self) -> bool

Returns true if the font as an opsz axis.

This is a quicker check than scanning the axes.

pub fn charmap_index(&self) -> CharmapIndex

Returns the index used for constructing a Charmap for this font.
