[−][src]Struct image::tiff::TIFFDecoder
The representation of a TIFF decoder
Currently does not support decoding of interlaced images
Methods
impl<R: Read + Seek> TIFFDecoder<R>[src]
pub fn new(r: R) -> ImageResult<TIFFDecoder<R>>[src]
Create a new decoder that decodes from the stream r
pub fn init(self) -> ImageResult<TIFFDecoder<R>>[src]
Initializes the decoder.
pub fn next_image(self) -> ImageResult<TIFFDecoder<R>>[src]
Reads in the next image.
If there is no further image in the TIFF file a format error is returned.
To determine whether there are more images call TIFFDecoder::more_images instead.
pub fn more_images(&self) -> bool[src]
Returns true if there is at least one more image available.
pub fn byte_order(&self) -> ByteOrder[src]
Returns the byte_order
pub fn read_short(&mut self) -> Result<u16, Error>[src]
Reads a TIFF short value
pub fn read_long(&mut self) -> Result<u32, Error>[src]
Reads a TIFF long value
pub fn read_offset(&mut self) -> Result<[u8; 4], Error>[src]
Reads a TIFF IFA offset/value field
pub fn goto_offset(&mut self, offset: u32) -> Result<()>[src]
Moves the cursor to the specified offset

x: u32,
y: u32,
length: u32,
width: u32
) -> ImageResult<Vec<u8>>
