Implementations

impl<'a> AxisValueSubtable<'a>

pub fn value(&self) -> Option<Fixed>

Returns the value from an axis value subtable.

For formats 1 and 3 the value is returned, for formats 2 and 4 None is returned as there is no single value associated with those formats.

pub fn contains(&self, value: Fixed) -> bool

Returns true if the axis subtable either is the value or is a range that contains the value passed in as an argument.

Note: this will always return false for format 4 subtables as they may contain multiple axes.

pub fn name_id(&self) -> u16

Returns the associated name ID.

pub fn is_elidable(&self) -> bool

Returns true if the axis subtable has the ELIDABLE_AXIS_VALUE_NAME flag set.

pub fn is_older_sibling(&self) -> bool

Returns true if the axis subtable has the OLDER_SIBLING_FONT_ATTRIBUTE flag set.
