com.accusoft.imagegear.formats.ImGearNativeDataTypes or com.accusoft.imagegear.formats.dicom.ImGearDICOMValueRepresentations enumeration value, passed as System.Object.

When metadata is loaded from a file, all leaves have this field set to explicit values.

When the application creates a leaf, it can either specify an explicit NativeType value or use the default value com.accusoft.imagegear.formats.ImGearNativeDataTypes.UNKNOWN.

At the time of image saving, most file formats ignore this field and use the file format's standard types for metadata tags. Two file formats take NativeType field into account:

• TIFF format filter saves tags according to the value specified by the NativeType field. If NativeType of a tag is com.accusoft.imagegear.formats.ImGearNativeDataTypes.UNKNOWN, TIFF filter skips the tag.
• DICOM format filter saves tags according to the value specified by the NativeType field. If NativeType of a tag is com.accusoft.imagegear.formats.ImGearNativeDataTypes.UNKNOWN, DICOM filter looks up the native type from its Data Dictionary. If the value is not found, it saves the tag as com.accusoft.imagegear.formats.dicom.ImGearDICOMValueRepresentations.Unknown.
