/*
 * File:   StackReader.h
 * Author: Marc
 *
 * Created on October 27, 2010, 4:32 PM
 *
 * used to read compressed stacks (generated by LinearStackCompressor or its subclasses)
 * from disk
 * this is the highest level reading function in the library;
 *
 * create the stackreader by passing a file name
 * access frames using the getFrame command
 * generate a meta data file using getSupplementalData
 *
 * in separate projects:
 * see also the supplemental dll wrapper: StackReaderWrapper
 * see also the example movie player: StackPlayer
 *
 * example usage:
 *   StackReader sr("\\\\labnas2\\Phototaxis\\exponentialstack.mmf"); //open stack for reading
 *   sr.createSupplementalDataFile("c:\\testcs5_dat.dat"); //create a metadata file
 *   sr.playMovie(); //play a movie on the screen
