Hello,

Does the TIFF specification require that fields such as first IFD offset, number of tags in a directory, tag structure and next IFD offset must be written at word aligned position in TIFF file?

In other words - when writing these fields to a TIFF file, do they have to be written in even bytes of data stream and some padding is required to follow the specification?

I have read the TIFF specification but haven't found anything about that. When searching in libTIFF sources I've found a comment in tiff.h, but only about positioning of tag data:

"[...] The values associated with each entry are disjoint and may appear anywhere in the file (so long as they are placed on a word boundary) [...]".

Can anyone put some light on that?

Thanks in advance,

Kind regards
