Description
Used in the TIFF-FX standard to point to an IFD containing tags that are globally applicable to the complete TIFF file.
It is recommended that a TIFF writer place this field in the first IFD, where a TIFF reader would find it quickly.
Each field in the GlobalParametersIFD is a TIFF field that is legal in any IFD. Required baseline fields should not be located in the GlobalParametersIFD, but should be in each image IFD. If a conflict exists between fields in the GlobalParametersIFD and in the image IFDs, then the data in the image IFD shall prevail.
