CSJ2K.j2k.fileformat.reader.FileFormatReader

FileFormatReader Class

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.
