Undefined = 7

8-bit byte that may contain anything

SShort = 8

16-bit signed integer

SLong = 9

32-bit signed integer

SRational = 10

Two SLONGs: numerator and denominator

Float = 11

Single precision IEEE floating point (4 bytes)

Double = 12

Double precision IEEE floating point (8 bytes)

Ifd = 13

32-bit unsigned integer offset to IFD

Long8 = 16

64-bit unsigned integer (BigTIFF)

SLong8 = 17

64-bit signed integer (BigTIFF)

Ifd8 = 18

64-bit unsigned integer offset to IFD (BigTIFF)

Implementations

impl TiffType

pub fn from_u16(value: u16) -> Option<Self>

Parse a type code from u16, returning None for unknown types.

pub fn size(&self) -> usize

Returns the size in bytes of a single element of this type.

pub fn fits_inline(&self, count: u32) -> bool

Returns whether a value of this type with the given count fits inline in an IFD entry.

Standard TIFF IFD entries have 4 bytes for the value/offset field. If the total data size fits in 4 bytes, it’s stored inline.

pub fn fits_inline_bigtiff(&self, count: u64) -> bool

Returns whether a value of this type with the given count fits inline in a BigTIFF entry.

BigTIFF IFD entries have 8 bytes for the value/offset field.
