Class IFDMetadata

java.lang.Object

ome.jxr.ifd.IFDMetadata

public class IFDMetadata
extends Object

Provides access to metadata extracted from the IFD part of a JPEG XR file. Adds simple logic to translate the raw byte data into primitive data types. The getters don't return primitive language types, so as to allow returning null. That value indicates a missing metadata element and cannot be confused with a numerical value (e.g. 0). This class also verifies value validity on a very basic level (no inferring of metadata value combination meanings), and where needed - returns a default as dictated by the ITU-T specification.
