Struct tiff::encoder::DirectoryEncoder

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

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

Write a single ifd tag.

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

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

Write out the ifd directory.
