Rationals(Vec<Rational>)

RATIONAL values

SBytes(Vec<i8>)

SBYTE values (i8)

Undefined(Vec<u8>)

UNDEFINED values (raw bytes)

SShorts(Vec<i16>)

SSHORT values (i16)

SLongs(Vec<i32>)

SLONG values (i32)

SRationals(Vec<SRational>)

SLong8s(Vec<i64>)

SLONG8 values (i64, BigTIFF)

Implementations

impl TiffValue

pub fn as_u32(&self) -> Option<u32>

Get as a single u32 value, if applicable.

pub fn first_u32(&self) -> Option<u32>

Get the first element as u32, useful for array tags like BitsPerSample.

pub fn as_u32_vec(&self) -> Option<Vec<u32>>

Get as a Vec, coercing numeric types if possible.

pub fn as_u64(&self) -> Option<u64>

Get as a single u64 value, if applicable.

pub fn as_u64_vec(&self) -> Option<Vec<u64>>

Get as a Vec, coercing numeric types if possible.

pub fn as_f64_vec(&self) -> Option<Vec<f64>>

Get as a Vec, coercing numeric types if possible. Supports Rationals, SRationals, Floats, Doubles, and integer types.

pub fn as_str(&self) -> Option<&str>

Get as string, if this is an ASCII value.

pub fn len(&self) -> usize

Get the number of elements in this value.

pub fn is_empty(&self) -> bool

Check if the value is empty.

Trait Implementations

impl Clone for TiffValue

fn clone(&self) -> TiffValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TiffValue

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

Formats the value using the given formatter.

impl PartialEq for TiffValue

fn eq(&self, other: &TiffValue) -> 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.
