Thanks for the tip! Bob Friesenhahn...

I will explore Tiffcp as well.

Thanks,

Basically

  1. I am reading input image (input_image.tiff) which has 17 tags and in Big-endian format and
  2. Then I wrote the same image (input_image.tiff) to a new image (written_image.tiff) using *Tiffopen(file, "w")*
  3. Now I got only 12 tags (instead of 17 tags) in Little-endian format when I read the written image (written_image.tiff)

If you use a utility like tiffcp then you are more likely to have most/all the tags in the output file.

If you want to preserve tags, then your writer will need to transcribe them. When you write a TIFF file using libtiff you are writing a new file.
