R: Read,
impl<R> QoiDecoder<R>where
R: Read,
sourcepub fn new(reader: R) -> ImageResult<Self>
pub fn new(reader: R) -> ImageResult<Self>
Creates a new decoder that decodes from the stream reader
Trait Implementations§

impl<'a, R: Read + 'a> ImageDecoder<'a> for QoiDecoder<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 into_reader(self) -> ImageResult<Self::Reader>
fn into_reader(self) -> ImageResult<Self::Reader>
👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989
Returns a reader that can be used to obtain the bytes of the image. For the best
performance, always try to read at least
scanline_bytes from the reader at a time. Reading
fewer bytes will cause the reader to perform internal buffering.source§fn original_color_type(&self) -> ExtendedColorType
fn original_color_type(&self) -> ExtendedColorType
Returns the color type of the image file before decoding
source§fn icc_profile(&mut self) -> Option<Vec<u8>>
fn icc_profile(&mut self) -> Option<Vec<u8>>
Returns the ICC color profile embedded in the image Read more
source§fn total_bytes(&self) -> u64
fn total_bytes(&self) -> u64
Returns the total number of bytes in the decoded image. Read more
source§fn scanline_bytes(&self) -> u64
fn scanline_bytes(&self) -> u64
👎Deprecated: Planned for removal. See https://github.com/image-rs/image/issues/1989
Returns the minimum number of bytes that can be efficiently read from this decoder. This may
be as few as 1 or as many as
total_bytes().source§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

self,
buf: &mut [u8],

) -> ImageResult<()>
fn read_image_with_progress<F: Fn(Progress)>( self, buf: &mut [u8], progress_callback: F, ) -> ImageResult<()>
👎Deprecated: Use read_image instead. See https://github.com/image-rs/image/issues/1989
Same as
read_image but periodically calls the provided callback to give updates on loading
progress.source§fn set_limits(&mut self, limits: Limits) -> ImageResult<()>
