I'm not aware of any way of clearing a tag completely from the directory either. In fact, "in place" update of a TIFF file on disk is still a relatively experimental area. In the past before in-place update there was never a compelling need to delete tags from an in memory directory since you could update a file on disk (other than appending new images).

The more conventional approach though is to copy the file you want to change to a new file, and just avoid copying anything you don't want in the new file.

wouldn't blind copying break tag data offsets?
