ByteOrder

Enum ByteOrder 

Source
pub enum ByteOrder {
    LittleEndian,
    BigEndian,
}
Expand description

Byte order of a TIFF stream, named by the two-byte order mark at the start of the header.

Every scalar in the stream — IFD offsets, entry counts, and multi-byte values — is read and written in this order. Unlike most binary image formats (which fix one endianness), TIFF records its own, so a reader must thread the ByteOrder through every access.

Variants§

§

LittleEndian

Little-endian (II, 0x4949): least-significant byte first.

§

BigEndian

Big-endian (MM, 0x4D4D): most-significant byte first.

Implementations§

Source§

impl ByteOrder

Source

pub fn u16(self, b: [u8; 2]) -> u16
