Struct tiff::decoder::Decoder[−][src]

pub struct Decoder<R> where
    R: Read + Seek,  { /* fields omitted */ }

The representation of a TIFF decoder

Currently does not support decoding of interlaced images

Implementations

`impl<R: Read + Seek> Decoder<R>`[src]

`pub fn new(r: R) -> TiffResult<Decoder<R>>`[src]

Create a new decoder that decodes from the stream r

`pub fn with_limits(self, limits: Limits) -> Decoder<R>`[src]

`pub fn dimensions(&mut self) -> TiffResult<(u32, u32)>`[src]

`pub fn colortype(&mut self) -> TiffResult<ColorType>`[src]

`pub fn init(self) -> TiffResult<Decoder<R>>`[src]

Initializes the decoder.

`pub fn next_image(&mut self) -> TiffResult<()>`[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_ifd_offset(&mut self) -> Result<u64, Error>`[src]

`pub fn read_byte(&mut self) -> Result<u8, Error>`[src]

Reads a TIFF byte value

`pub fn read_short(&mut self) -> Result<u16, Error>`[src]

Reads a TIFF short value

`pub fn read_sshort(&mut self) -> Result<i16, Error>`[src]

Reads a TIFF sshort value

`pub fn read_long(&mut self) -> Result<u32, Error>`[src]

Reads a TIFF long value

`pub fn read_slong(&mut self) -> Result<i32, Error>`[src]

Reads a TIFF slong value

`pub fn read_float(&mut self) -> Result<f32, Error>`[src]

Reads a TIFF float value

`pub fn read_double(&mut self) -> Result<f64, Error>`[src]

Reads a TIFF double value

`pub fn read_long8(&mut self) -> Result<u64, Error>`[src]

`pub fn read_string(&mut self, length: usize) -> TiffResult<String>`[src]

Reads a string

`pub fn read_offset(&mut self) -> TiffResult<[u8; 4]>`[src]

Reads a TIFF IFA offset/value field

`pub fn read_offset_u64(&mut self) -> Result<[u8; 8], 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

`pub fn goto_offset_u64(&mut self, offset: u64) -> Result<()>`[src]

`pub fn find_tag(&mut self, tag: Tag) -> TiffResult<Option<Value>>`[src]

Tries to retrieve a tag. Return Ok(None) if the tag is not present.

`pub fn find_tag_unsigned<T: TryFrom<u64>>( &mut self, tag: Tag ) -> TiffResult<Option<T>>`[src]

Tries to retrieve a tag and convert it to the desired unsigned type.

`pub fn find_tag_unsigned_vec<T: TryFrom<u64>>( &mut self, tag: Tag ) -> TiffResult<Option<Vec<T>>>`[src]

Tries to retrieve a vector of all a tag’s values and convert them to the desired unsigned type.

`pub fn get_tag_unsigned<T: TryFrom<u64>>(&mut self, tag: Tag) -> TiffResult<T>`[src]

Tries to retrieve a tag and convert it to the desired unsigned type. Returns an error if the tag is not present.
