IfdChain

tiff_forge::ifd

Struct IfdChain 

Source 
pub struct IfdChain<O: OffsetSize = u32>(/* private fields */);
Expand description

An ordered list of Ifds, each pointing to the next one.

The last Ifd doesn’t point to any other.

Generic over O: OffsetSize to support both TIFF (u32) and BigTIFF (u64).

Because any IFD could technically point to a next one, in most functions that one would expect to input an Ifd, its parameters actually ask for an IfdChain.

Implementations§

Source§

impl<O: OffsetSize> IfdChain<O>

Source

pub fn new(ifds: Vec<Ifd<O>>) -> IfdChain<O>

Creates a new IfdChain from a vector of Ifds.

§Panics

The TIFF specification requires that each IFD must have at least one entry.

Trying to create an IfdChain with one or more empty Ifds will panic.

Source

pub fn single(ifd: Ifd<O>) -> IfdChain<O>

Creates a new IfdChain from a single Ifd.

§Panics

The TIFF specification requires that each IFD must have at least one entry.

Trying to create an IfdChain from an empty Ifd will panic.
