2003.09.30 14:57 "[Tiff] Reading thumbnail", by takamiyakita@yahoo.co.jp

Hi,

By reading TIFF Specification, full-size image is in IFD0 and thumbnail is in IFD1.

So, I was trying to get thumbnail data by calling TIFFSetDirectory(tifr,1) after calling TIFFOpen( ).

But TIFFSetDirectory(tifr,1) returned 0. IFD1 did not exist.

I created the tiff file by Adobe PhotoShop.

what is wrong?
please any infomation.

thank you.
