Struct LocationRef

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

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 [NormalizedCoord]) -> Self
