Public Fields

Name Description

	Name	Description
	format	Identifier of the File format to which the metadata belongs. com.accusoft.imagegear.formats.ImGearMetadataFormats enumeration It is possible for a metadata tree to contain subtrees defined in another metadata format. For example, JPEG metadata tree may contain subtrees containing EXIF or IPTC metadata. com.accusoft.imagegear.formats.ImGearFormats.UNKNOWN means custom (unknown) format. com.accusoft.imagegear.formats.ImGearMetadataFormats (Inherited from com.accusoft.imagegear.core.ImGearMetadataNode)
	nativeType	Specifies the type of data stored in a leaf, as it was stored in the image file or should be saved to the image file. 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.
	tag	Represents identifier of metadata node for particular file format. Integer value Identifies what kind of data is stored in metadata node. Specific for particular file format. Values for the tags are taken from tag list of file formats, represented in ImageGear for Java as `ImGearFORMATTagIDs` (where FORMAT is BMP, TIFF, etc.) enumerations. (Inherited from com.accusoft.imagegear.core.ImGearMetadataNode)

Identifier of the File format to which the metadata belongs.

com.accusoft.imagegear.formats.ImGearMetadataFormats enumeration

It is possible for a metadata tree to contain subtrees defined in another metadata format. For example, JPEG metadata tree may contain subtrees containing EXIF or IPTC metadata.

com.accusoft.imagegear.formats.ImGearFormats.UNKNOWN means custom (unknown) format.

com.accusoft.imagegear.formats.ImGearMetadataFormats

(Inherited from com.accusoft.imagegear.core.ImGearMetadataNode)

nativeType

Specifies the type of data stored in a leaf, as it was stored in the image file or should be saved to the image file.

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.

tag

Represents identifier of metadata node for particular file format.

Integer value

Identifies what kind of data is stored in metadata node. Specific for particular file format.

Values for the tags are taken from tag list of file formats, represented in ImageGear for Java as ImGearFORMATTagIDs (where FORMAT is BMP, TIFF, etc.) enumerations.
