LocationRef

Struct LocationRef 

pub struct LocationRef<'a>(/* private fields */);
Expand description

Reference to an ordered sequence of normalized variation coordinates.

To convert from user coordinates see crate::AxisCollection::location.

This type represents a position in the variation space where each coordinate corresponds to an axis (in the same order as the fvar table) and is a normalized value in the range [-1..1].

See Coordinate Scales and Normalization for further details.

If the array is larger in length than the number of axes, extraneous values are ignored. If it is smaller, unrepresented axes are assumed to be at their default positions (i.e. 0).

A value of this type constructed with default() represents the default position for each axis.

Normalized coordinates are ignored for non-variable fonts.

Implementations§

§

impl<'a> LocationRef<'a>

pub fn new(coords: &'a [F2Dot14]) -> LocationRef<'a>

Creates a new sequence of normalized coordinates from the given array.

pub fn coords(&self) -> &'a [F2Dot14]

Returns the underlying array of normalized coordinates.

pub fn is_default(&self) -> bool

Returns true if this represents the default location in variation space.

This is represented a set of normalized coordinates that is either empty or contains all zeroes.
