Struct FWord 

pub struct FWord(/* private fields */);

16-bit signed quantity in font design units.

Implementations

impl FWord

pub const fn new(raw: i16) -> Self

pub const fn to_i16(self) -> i16

pub const fn to_fixed(self) -> Fixed

Converts this number to a 16.16 fixed point value.

pub fn apply_delta(self, delta: F48Dot16) -> f32

Applies an item variation delta, returning the varied value as a single precision floating point number.

A delta for a font unit valued target is already in font units, so the accumulated 48.16 delta applies unscaled. The result is intentionally not rounded back to an integer.

pub const fn to_be_bytes(self) -> [u8; 2]

The representation of this number as a big-endian byte array.
