Struct image::tiff::TIFFDecoder [−] [src]

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

The representation of a TIFF decoder

Currently does not support decoding of interlaced images

Methods

`impl<R: Read + 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) -> Result<u16, Error>`

Reads a TIFF short value

`fn read_long(&mut self) -> Result<u32, Error>`

Reads a TIFF long value

`fn read_offset(&mut self) -> Result<[u8; 4], Error>`

Reads a TIFF IFA offset/value field

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

Moves the cursor to the specified offset
