Implementations§
source§impl<R: Read> GifDecoder<R>
impl<R: Read> GifDecoder<R>
sourcepub fn new(r: R) -> ImageResult<GifDecoder<R>>
pub fn new(r: R) -> ImageResult<GifDecoder<R>>
Creates a new decoder that decodes the input steam r
sourcepub fn with_limits(r: R, limits: Limits) -> ImageResult<GifDecoder<R>>
👎Deprecated since 0.24.8: Use new
followed by set_limits
instead
pub fn with_limits(r: R, limits: Limits) -> ImageResult<GifDecoder<R>>
new
followed by set_limits
insteadCreates a new decoder that decodes the input steam r
, using limits limits

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

buf: &mut [u8],

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
