[−][src]Module tiff_encoder::ifd
Module to manipulate IFDs and their entries.
An image file directory (IFD) contains information about the image, as well as pointers to the actual image data (both stored as entries).
In a TIFF file, an IFD may point to another IFD with its last 4
bytes. To abstract the user of this crate from the position of each
structure in the file, this link between Ifd
s is represented by
an IfdChain
. 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
.
