Expand description

Trait for types that can be encoded in a tiff file

Required Associated Constants

source

Required Methods

source

fn count(&self) -> usize

source

fn data(&self) -> Cow<'_, [u8 ]>

Access this value as an contiguous sequence of bytes. If their is no trivial representation, allocate it on the heap.

Provided Methods

source

fn bytes(&self) -> usize

source

fn write<W: Write>(&self, writer: &mut TiffWriter<W>) -> TiffResult<()>

Write this value to a TiffWriter. While the default implementation will work in all cases, it may require unnecessary allocations. The written bytes of any custom implementation MUST be the same as yielded by self.data().
