I believe you would call the _TIFFFindFieldInfo() function:

Thank you for excellent reply.

As a sidenote, I'm seeing this declaration in tiffio.h:

extern const TIFFFieldInfo* TIFFFindFieldInfo(TIFF*, ttag_t, TIFFDataType);

This seems covered by this define in tif_dir.h:

#define _TIFFFindFieldInfo     TIFFFindFieldInfo

Is why I thought the function, or at least the version without underscore prefix, was external in LibTiff. I've also treated it as external in LibTiffDelphi.

Joris,

Umm... cool. I wonder why it is complicated like this. Worse yet, I wonder if I did this? I suspect it used to be internal (hence the underscore) and the #define just was a way of transitioning it to external while not having to hunt down all the internal locations that called it _TIFFFindFieldInfo. Still it seems unnecessarily messy.

Best regards,
