## Detailed Description

Class to represent a File Meta Information.

FileMetaInformation is a Explicit Structured Set. Whenever the file contains an ImplicitDataElement DataSet, a conversion will take place.

Definition: The File Meta Information includes identifying information on the encapsulated Data Set. This header consists of a 128 byte File Preamble, followed by a 4 byte DICOM prefix, followed by the File Meta Elements shown in Table 7.1-1. This header shall be present in every DICOM file.

Examples:

  GenAllVR.cxx, GenFakeIdentifyFile.cxx, LargeVRDSExplicit.cxx, ReadAndDumpDICOMDIR.cxx, and TestReader.cxx.
