Implementations§

source§

impl<R> QoiDecoder<R>
where R: Read,

source

pub fn new(reader: R) -> ImageResult<Self>

Creates a new decoder that decodes from the stream reader

Trait Implementations§

source§

impl<R: Read> ImageDecoder for QoiDecoder<R>

source§

fn dimensions(&self) -> (u32, u32)

Returns a tuple containing the width and height of the image
source§

fn color_type(&self) -> ColorType

Returns the color type of the image data produced by this decoder
source§

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<()>

Use read_image instead; this method is an implementation detail needed so the trait can be object safe. Read more
source§

fn original_color_type(&self) -> ExtendedColorType

Returns the color type of the image file before decoding
source§

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 more
source§

fn total_bytes(&self) -> u64

Returns the total number of bytes in the decoded image. Read more
source§

fn set_limits(&mut self, limits: Limits) -> ImageResult<()>

Set the decoder to have the specified limits. See Limits for the different kinds of limits that is possible to set. Read more
