Class IFD

java.lang.Object
org.monte.media.tiff.IFD
public class IFD extends Object
Represents a TIFF Image File Directory (IFD).

An IFD consists of a 2-byte count of the number of directory entries (i.e., the number of fields), followed by a sequence of 12-byte field entries, followed by a 4-byte offset of the next IFD (or 0 if none).

There must be at least 1 IFD in a TIFF file and each IFD must have at least one entry.
