2006.10.11 07:41 "Please ignore earlier mail / Handling Of SubIFD in Libtiff Ver 3.8.2", by Anurag Singh

Hello All

I am using libtiff 3.8.2 , i have a tiff image which have one subifd. But
whatever i have seen libtiff is not working for subifds.I got to know with
the help of tag viewer that this particular image have subifd, but after
reading whole image file TIFFDirectory structure doesn't show any
information about SubIFD.

I have debug the whole tiff library but i didnt get any handling for tag
TIFF_SUBIFD(330), if libtiff is reading this  tag as a normal tag and then
finally the value of these members (uint16 td_nsubifd, uint32* td_subifd) of
TIFFDirectory structure are 0.

it's mean there are something missing or may be some other way to handle it.
Please let me know that how to deal with subIFD.

Thanks In Advance
Anurag Singh
