Struct Axis 

pub struct Axis {
    pub name: String,
    pub tag: Tag,
    pub min: UserCoord,
    pub default: UserCoord,
    pub max: UserCoord,
    pub hidden: bool,
    pub converter: CoordConverter,
    pub localized_names: HashMap<String, String>,
}

A variable font axis.

Fields

name: String

A human-readable name, like ‘Weight’.

tag: Tag

The axis tag, like ‘wght’.

min: UserCoord

The minimum value for this axis, in UserSpace.

default: UserCoord

The default value for this axis, in UserSpace.

max: UserCoord

The max value for this axis, in UserSpace.

hidden: bool

converter: CoordConverter

localized_names: HashMap<String, String>

Localized names for the axis, e.g. {"en": "Weight"}

Implementations

impl Axis

pub fn is_point(&self) -> bool

pub fn default_converter(&self) -> CoordConverter

Initialize a CoordConverter for the default normalization from this axis user space.

pub fn ui_label_name(&self) -> &str

Display name for the axis.

Some frontends (e.g. designspace) support the notion of an axis’ UI label name distinct from the axis name; the former is used for displaying the axis in UI and can be localised, whereas the latter is only used for internal cross-references. In Designspace documents, these are stored in the axes’ <labelname> elements. FontTools uses these to build the name records associated with axis names referenced by fvar and STAT tables, or else falls back to the axis.name. But even when the labelnames are ommited, there’s a special group of registered axis names that were common in old MutatorMath source files before the <labelname> element itself got standardised, which continue to receive a special treatment in fonttools: i.e., the lowercase, shortened name gets replaced with a title-case, expanded one (e.g. ‘weight’ => ‘Weight’, ‘optical’ => ‘Optical Size’ etc.). For the sake of matching fontmake (which uses fonttools), we do the same here.

Trait Implementations

impl Clone for Axis

fn clone(&self) -> Axis

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Axis

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Axis

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl FromIterator<Axis> for Axes

fn from_iter<T: IntoIterator<Item = Axis>>(iter: T) -> Self

Creates a value from an iterator.

impl PartialEq for Axis

fn eq(&self, other: &Axis) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Axis

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Axis
