Struct image::tiff::TIFFDecoder
source · Expand description
Decoder for TIFF images.
Implementations
sourceimpl<R> TIFFDecoder<R>where
R: Read + Seek,
impl<R> TIFFDecoder<R>where
R: Read + Seek,
sourcepub fn new(r: R) -> Result<TIFFDecoder<R>, ImageError>
pub fn new(r: R) -> Result<TIFFDecoder<R>, ImageError>
Create a new TIFFDecoder.

impl<R: Read + Seek> ImageDecoder for TIFFDecoder<R>
sourcefn dimensions(&self) -> (u64, u64)
fn dimensions(&self) -> (u64, u64)
Returns a tuple containing the width and height of the image
sourcefn into_reader(self) -> ImageResult<Self::Reader>
fn into_reader(self) -> ImageResult<Self::Reader>
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. Read moresourcefn read_image(self) -> ImageResult<Vec<u8>>
fn read_image(self) -> ImageResult<Vec<u8>>
Returns all the bytes in the image.
sourcefn row_bytes(&self) -> u64
fn row_bytes(&self) -> u64
Returns the number of bytes in a single row of the image. All decoders will pad image rows
to a byte boundary. Read more
sourcefn total_bytes(&self) -> u64
fn total_bytes(&self) -> u64
Returns the total number of bytes in the image.
sourcefn scanline_bytes(&self) -> u64
fn scanline_bytes(&self) -> u64
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()
. Read moresourcefn read_image_with_progress<F: Fn(Progress)>(
self,
progress_callback: F
) -> ImageResult<Vec<u8>>
fn read_image_with_progress<F: Fn(Progress)>(
self,
progress_callback: F
) -> ImageResult<Vec<u8>>
Same as
read_image
but periodically calls the provided callback to give updates on loading
progress. Read moreAuto Trait Implementations
