I have an empty tags which want to remove from tif wout copying process. I tried TIFFSetField(tif, TIFFTAG_DOCUMENTNAME, ""); but tag still seats in the file. Is it possible to drop an empty ascii tags?

Gennady,

I am afraid there is no a clean way to purge empty tags. I don't want to recommend you the way with removing old directory using TIFFUnlinkDirectory() because it involves rewriting the whole data chunk including strip/tile arrays. You can add an entry to our Bugzilla requesting the function for field dropping.

Best regards,

Andrey
