Struct VariationRegion

pub struct VariationRegion<'a> {
    pub region_axes: &'a [RegionAxisCoordinates],
}

The VariationRegion record

Fields

region_axes: &'a [RegionAxisCoordinates]

Array of region axis coordinates records, in the order of axes given in the ‘fvar’ table.

Implementations

impl<'a> VariationRegion<'a>

pub fn region_axes(&self) -> &'a [RegionAxisCoordinates]

Array of region axis coordinates records, in the order of axes given in the ‘fvar’ table.

impl<'a> VariationRegion<'a>

pub fn read(data: FontData<'a>, axis_count: u16) -> Result<Self, ReadError>

A constructor that requires additional arguments.

This type requires some external state in order to be parsed.

impl VariationRegion<'_>

pub fn compute_scalar(&self, coords: &[F2Dot14]) -> Fixed

Computes a scalar value for this region and the specified normalized variation coordinates.

pub fn compute_scalar_f32(&self, coords: &[F2Dot14]) -> f32

Computes a floating point scalar value for this region and the specified normalized variation coordinates.

Trait Implementations

impl<'a> Clone for VariationRegion<'a>

fn clone(&self) -> VariationRegion<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl ComputeSize for VariationRegion<'_>

fn compute_size(args: &u16) -> Result<usize, ReadError>

Compute the number of bytes required to represent this type.

impl<'a> Debug for VariationRegion<'a>

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

Formats the value using the given formatter.

impl<'a> FontReadWithArgs<'a> for VariationRegion<'a>

fn read_with_args(data: FontData<'a>, args: &u16) -> Result<Self, ReadError>

read an item, using the provided args.

impl<'a> Hash for VariationRegion<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> Ord for VariationRegion<'a>

fn cmp(&self, other: &VariationRegion<'a>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl<'a> PartialEq for VariationRegion<'a>

fn eq(&self, other: &VariationRegion<'a>) -> 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<'a> PartialOrd for VariationRegion<'a>

fn partial_cmp(&self, other: &VariationRegion<'a>) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl ReadArgs for VariationRegion<'_>

type Args = u16
