Hi Hubert,
I seem to have come across a bug in Adobe's code for embedding XMP in
the TIFF format. The spec[1] says that the XMLPacket tag has type BYTE,
but Adobe assigns a type of UNDEFINED. libtiff complains and is unable
to read the XMP when given the wrong type.
In TIFF_Handler.cpp, changing
this->tiffMgr.SetTag ( kTIFF_PrimaryIFD, kTIFF_XMP, kTIFF_UndefinedType,
this->xmpPacket.size(), this->xmpPacket.c_str() );
to
this->tiffMgr.SetTag ( kTIFF_PrimaryIFD, kTIFF_XMP, kTIFF_ByteType,
this->xmpPacket.size(), this->xmpPacket.c_str() );
solves the problems I'm having.
This should be passed on to Adobe. Do you know who to contact to get
this fixed?
Cheers,
Jason
