Implementations§

source§

impl TupleIndex

source

pub const EMBEDDED_PEAK_TUPLE: u16 = 32_768u16

Flag indicating that this tuple variation header includes an embedded peak tuple record, immediately after the tupleIndex field.

If set, the low 12 bits of the tupleIndex value are ignored.

Note that this must always be set within the ‘cvar’ table.

source

pub const INTERMEDIATE_REGION: u16 = 16_384u16

Flag indicating that this tuple variation table applies to an intermediate region within the variation space.

If set, the header includes the two intermediate-region, start and end tuple records, immediately after the peak tuple record (if present).

source

pub const PRIVATE_POINT_NUMBERS: u16 = 8_192u16

Flag indicating that the serialized data for this tuple variation table includes packed “point” number data.

If set, this tuple variation table uses that number data; if clear, this tuple variation table uses shared number data found at the start of the serialized data for this glyph variation data or ‘cvar’ table.

source

pub const TUPLE_INDEX_MASK: u16 = 4_095u16

Mask for the low 12 bits to give the shared tuple records index.

source

pub fn bits(self) -> u16

source

pub fn from_bits(bits: u16) -> Self

source

pub fn embedded_peak_tuple(self) -> bool

true if the header includes an embedded peak tuple.

source

pub fn intermediate_region(self) -> bool

true if the header includes the two intermediate region tuple records.

source

pub fn private_point_numbers(self) -> bool

true if the data for this table includes packed point number data.

source

pub fn tuple_records_index(self) -> Option<u16>
