Note also that, when creating the TIFF output set from scratch, if I use the
following I cannot pick up the values in
[metadata-extractor|https://github.com/drewnoakes/metadata-extractor]:
{code:java}
TiffOutputDirectory exifDirectory = tiffOutputSet.getOrCreateExifDirectory()
{code}
Instead I have to use this:
{code:java}
TiffOutputDirectory exifDirectory = tiffOutputSet.getOrCreateRootDirectory()
{code}
Again this doesn't fix the problem. It's some counter-intuitive call I have to
make to get
[metadata-extractor|https://github.com/drewnoakes/metadata-extractor] to see
any values at all.
Apache Commons Imaging is corrupting my image metadata, and its documentation
is incomplete. I'm stuck.

If I use the same code with the {{ImageDescription}} field, it seems to work:
{code:java}
TagInfoAscii EXIF_IMAGE_DESCRIPTION_TAG_INFO = new
TagInfoAscii("ImageDescription", 0x010E, -1,
TiffDirectoryType.EXIF_DIRECTORY_IFD0); //ImageDescription (270, 0x010E)
{code}
Note that this doesn't fix the problem. I want to write the {{XPTitle}} field.
Moreover not knowing what the problem is, I don't know if Apache Common Imaging
is going to arbitrarily corrupt some of my Exif fields, and when.
