Hi list,

should it be possible to extend the tags of (the first directory of) an existing tiff file opened in "a"ppend mode?

What I'm trying to do is:
+ open an existing tiff file with TIFFOpen(...,"a")
+ create an array of TIFFFieldInfo
+ call TIFFMergeFieldInfo() with this array and count
+ Write some (string) tags that were defined in the array
+ close the tiff handle with TIFFClose()

It seems that TIFFClose() hangs somewhere and doesn't return, which is why I suspect that what I'm trying to do is impossible.
