Struct ImageCodec

pub struct ImageCodec { /* private fields */ }

Provides a unified interface for inspecting image data and creating image decoders & encoders.

Implementations

impl ImageCodec

pub fn create_decoder(&self) -> Option<ImageDecoder>

Creates an ImageDecoder for this codec.

pub fn create_encoder(&self) -> Option<ImageEncoder>

Creates an ImageEncoder for this codec.

pub fn inspect_data<R: AsRef<[u8]>>(&self, data: R) -> u32

Inspects the given data blob and determines how likely it is that the file belongs to this codec.

pub fn built_in_codecs() -> Array<ImageCodec>

Returns the blend2d builtin codecs.

pub fn add_to_built_in(codec: &ImageCodec)

Adds a codec to the built in codecs list.

pub fn remove_from_built_in(codec: &ImageCodec)

Removes the codec from the built in codecs list.

pub fn name(&self) -> &str

The codec’s name.

pub fn vendor(&self) -> &str

The codec’s vendor.

pub fn mime_type(&self) -> &str

The codec’s mime-type.

pub fn extensions(&self) -> impl Iterator<Item = &str>

The codec’s file extensions.

pub fn features(&self) -> ImageCodecFeatures

The codec’s features.

Trait Implementations

impl Clone for ImageCodec

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ImageCodec

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

Formats the value using the given formatter.

impl Drop for ImageCodec

fn drop(&mut self)

Executes the destructor for this type.

impl PartialEq for ImageCodec

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