C# Class CSJ2K.j2k.fileformat.reader.FileFormatReader

This class reads the file format wrapper that may or may not exist around a valid JPEG 2000 codestream. Since no information from the file format is used in the actual decoding, this class simply goes through the file and finds the first valid codestream.

Méthode Description
FileFormatReader ( RandomAccessIO in_Renamed ) : System

The constructor of the FileFormatReader
readContiguousCodeStreamBox ( long pos, int length, long longLength ) : bool

This method skips the Contiguous codestream box and adds position of contiguous codestream to a vector
readFileFormat ( ) : void

This method checks whether the given RandomAccessIO is a valid JP2 file and if so finds the first codestream in the file. Currently, the information in the codestream is not used
readFileTypeBox ( ) : bool

This method reads the File Type box.
readIntPropertyBox ( int length ) : void

This method reads the contents of the Intellectual property box
readJP2HeaderBox ( long pos, int length, long longLength ) : bool

This method reads the JP2Header box
readReaderRequirementsBox ( int length ) : void

This method reads the contents of the Reader requirements box
readUUIDBox ( int length ) : void

This method reads the contents of the Intellectual property box
readUUIDInfoBox ( int length ) : void

This method reads the contents of the Intellectual property box
readXMLBox ( int length ) : void

This method reads the contents of the XML box
