Hello.


If I take a "non-Intel" two-page TIFF end extract the second page to a stream (ExtractTIFFImageStream) and then try to read tags from this stream (TIETIFTagsReader.CreateFromStream(PageStream, 0)) I get an invalid value for the tag 258 (Tags.GetInteger(258)).

I have double checked, and the TIFF contains proper information. The TIETIFFTagsReader will read the correct value if I read the TIFF page directly. Only by following the above procedure and extracting a single page to a memory stream exhibits this problem.

I don't know what I was thinking by not including the sample in the first place.
I apologise.

I hope it will help.
