Struct image::tiff::TIFFDecoder

pub struct TIFFDecoder<R> where R: Reader + Seek {
    // some fields omitted
}

The representation of a PNG decoder

Currently does not support decoding of interlaced images

Methods

impl<R: Reader + Seek> TIFFDecoder<R>

fn new(r: R) -> ImageResult<TIFFDecoder<R>>

Create a new decoder that decodes from the stream r

fn init(self) -> ImageResult<TIFFDecoder<R>>

Initializes the decoder.

fn next_image(self) -> ImageResult<TIFFDecoder<R>>

Reads in the next image. If there is no further image in the TIFF file a format error is return. To determine whether there are more images call TIFFDecoder::more_images instead.

fn more_images(&self) -> bool

Returns true if there is at least one more image available.

fn byte_order(&self) -> ByteOrder

Returns the byte_order

fn read_short(&mut self) -> IoResult<u16>

Reads a TIFF short value

fn read_long(&mut self) -> IoResult<u32>

Reads a TIFF long value

fn read_offset(&mut self) -> IoResult<[u8; 4]>

Reads a TIFF IFA offset/value field

fn goto_offset(&mut self, offset: u32) -> IoResult<()>

Moves the cursor to the specified offset
