QUncompress can't read a file which was compressed with qCompress



  • Alright, all I want to do is to compress and uncompress a file with qCompress/qUncompress:

    @QCoreApplication a(argc, argv);
    QStringList args = QCoreApplication::arguments();

    if(args.count() > 1){

    if(args.at(1) == "-d"){//Decompress
    QFile source(args.at(2));
    if(source.open(QFile::ReadOnly)){
    QByteArray compressedData = source.readAll();
    QByteArray deCompressedData = qUncompress(compressedData);
    source.close();
    QFileInfo info(source);
    QDir destinationDir(info.dir());
    QFileInfo destinationInfo(destinationDir, info.baseName());

    QFile destination(destinationInfo.absoluteFilePath());
    destination.open(QFile::WriteOnly);
    QTextStream destStream(&destination);
    destStream << deCompressedData;
    destStream.flush();
    destination.close();
    

    }
    }
    else{//Compress
    QFile source(args.at(1));
    if(source.open(QFile::ReadOnly)){
    QByteArray compressedData = qCompress(source.readAll());
    source.close();
    QFileInfo info(source);
    QDir destinationDir(info.dir());
    QFileInfo destinationInfo(destinationDir, info.fileName() + ".gz");

    QFile destination(destinationInfo.absoluteFilePath());
    destination.open(QFile::WriteOnly);
    QTextStream destStream(&destination);
    destStream << compressedData;
    destStream.flush();
    destination.close();
    

    }
    }
    }@

    Oddly, qUncompress gives me "qUncompress: Z_DATA_ERROR: Input Data is corrupted", eventhough the original data was compressed with qCompress?
