Hi all,

Can anyone advise if its possible to read a private IFD (using TIFFReadCustomDirectory or other) without knowing in-advance what the fields may be?

To explain further, I'm writing converters between a bespoke image stream and TIFF. Unfortunately the metadata in the bespoke stream can be a little inconsistent, hence I've written a dynamic IFD-writer to accommodate this, but got stumped with the TIFF reader: which expects a completed TIFFFieldArray before parsing: something I don't necessarily know in advance.

Any ideas?
