Struct tiff::encoder::compression::packbits::Packbits

pub struct Packbits;

Compressor that uses the Packbits¹ algorithm to compress bytes.

---

1. PackBits is often ineffective on continuous tone images, including many grayscale images. In such cases, it is better to leave the image uncompressed. ↩

Trait Implementations

impl Clone for Packbits

fn clone(&self) -> Packbits

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Compression for Packbits

const COMPRESSION_METHOD: CompressionMethod = CompressionMethod::PackBits

The corresponding tag to the algorithm.

fn get_algorithm(&self) -> Compressor

Method to optain a type that can store each variant of comression algorithm.

impl CompressionAlgorithm for Packbits

fn write_to<W: Write>( &mut self, writer: &mut W, bytes: &[u8] ) -> Result<u64, Error>

The algorithm writes data directly into the writer. It returns the total number of bytes written.

impl Debug for Packbits

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

Formats the value using the given formatter.

impl Default for Packbits

fn default() -> Packbits

Returns the “default value” for a type.

impl PartialEq<Packbits> for Packbits

fn eq(&self, other: &Packbits) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
