Struct tiff::encoder::DirectoryEncoder

source ·
pub struct DirectoryEncoder<'a, W: 'a + Write + Seek, K: TiffKind> {
    writer: &'a mut TiffWriter<W>,
    dropped: bool,
    ifd_pointer_pos: u64,
    ifd: BTreeMap<u16, DirectoryEntry<K::OffsetType>>,
}
Expand description

Low level interface to encode ifd directories.

You should call finish on this when you are finished with it. Encoding can silently fail while this is dropping.

Implementations§

source§

impl<'a, W: 'a + Write + Seek, K: TiffKind> DirectoryEncoder<'a, W, K>

source

fn new(writer: &'a mut TiffWriter<W>) -> TiffResult<Self>

source

pub fn write_tag<T: TiffValue>(&mut self, tag: Tag, value: T) -> TiffResult<()>

Write a single ifd tag.

source

fn write_directory(&mut self) -> TiffResult<u64>

source

pub fn write_data<T: TiffValue>(&mut self, value: T) -> TiffResult<u64>

Write some data to the tiff file, the offset of the data is returned.

This could be used to write tiff strips.

source

fn last_written(&self) -> u64

Provides the number of bytes written by the underlying TiffWriter during the last call.

source

fn finish_internal(&mut self) -> TiffResult<()>

source

pub fn finish(self) -> TiffResult<()>

Write out the ifd directory.
