pub struct AvifDecoder<R> { /* private fields */ }Available on (crate features
avif or avif-native) and crate feature avif-native only.Expand description
The AVIF specification defines an image derivative of the AV1 bitstream, an open video codec.
AVIF Decoder.
Reads one image into the chosen input.
Implementations§
Source§impl<R: Read> AvifDecoder<R>
impl<R: Read> AvifDecoder<R>
Sourcepub fn new(r: R) -> ImageResult<Self>
pub fn new(r: R) -> ImageResult<Self>
Create a new decoder that reads its input from r.
Trait Implementations§

impl<R: Read> ImageDecoder for AvifDecoder<R>
Source§fn dimensions(&self) -> (u32, u32)
fn dimensions(&self) -> (u32, u32)
Returns a tuple containing the width and height of the image
Source§fn color_type(&self) -> ColorType
fn color_type(&self) -> ColorType
Returns the color type of the image data produced by this decoder
Source§fn icc_profile(&mut self) -> ImageResult<Option<Vec<u8>>>
fn icc_profile(&mut self) -> ImageResult<Option<Vec<u8>>>
Returns the ICC color profile embedded in the image, or
Ok(None) if the image does not have one. Read moreSource§fn read_image(self, buf: &mut [u8]) -> ImageResult<()>
fn read_image(self, buf: &mut [u8]) -> ImageResult<()>
Returns all the bytes in the image. Read more
Source§fn read_image_boxed(self: Box<Self>, buf: &mut [u8]) -> ImageResult<()>
fn read_image_boxed(self: Box<Self>, buf: &mut [u8]) -> ImageResult<()>
Use
read_image instead; this method is an implementation detail needed so the trait can
be object safe. Read moreSource§fn original_color_type(&self) -> ExtendedColorType
fn original_color_type(&self) -> ExtendedColorType
Returns the color type of the image file before decoding
Source§fn exif_metadata(&mut self) -> ImageResult<Option<Vec<u8>>>
fn exif_metadata(&mut self) -> ImageResult<Option<Vec<u8>>>
Returns the raw Exif chunk, if it is present.
A third-party crate such as
kamadak-exif is required to actually parse it. Read moreSource§fn xmp_metadata(&mut self) -> ImageResult<Option<Vec<u8>>>
