DEFLATE algorithms supported by oxipng

Variants

Zlib

Use the Zlib/Miniz DEFLATE implementation

Fields of Zlib

compression: IndexSet<u8>

Which zlib compression levels to try on the file (1-9)

Default: 9

strategies: IndexSet<u8>

Which zlib compression strategies to try on the file (0-3)

Default: 0-3

window: u8

Window size to use when compressing the file, as 2^window bytes.

Doesn't affect compression but may affect speed and memory usage. 8-15 are valid values.

Default: 15

Zopfli

Use the better but slower Zopfli implementation

Libdeflater

Use libdeflater.

Trait Implementations

impl Clone for Deflaters

fn clone(&self) -> Deflaters

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Deflaters

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

Formats the value using the given formatter.

impl PartialEq<Deflaters> for Deflaters

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

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

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

This method tests for !=.
