Struct DirectoryEncoder 

pub struct DirectoryEncoder<'a, W: 'a + Write + Seek, K: TiffKind> { /* private fields */ }

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

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

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

Write a single ifd tag.

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.

pub fn set_parent(&mut self, offset: &DirectoryOffset<K>)

Define the parent directory.

Each directory has an offset based link to its successor, forming a linked list in the file. The encoder writes its own offset into the parent’s field when Self::finish is called or it is dropped. This redefines the parent. An offset representation of the parent must be acquired by finishing it with Self::finish_with_offsets.

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

Write out the ifd directory itself.

pub fn finish_with_offsets(self) -> TiffResult<DirectoryOffset<K>>

Trait Implementations

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

fn drop(&mut self)

Executes the destructor for this type.
