Нужно переделать JAVA в DELPHI

public static byte[] getBytesFromFile(File file) throws IOException
  {
    long length = file.length();
    if (length > 2147483647L)
    {
      throw new IOException("File is too large!");
    }
 
    byte[] bytes = new byte[(int)length];
 
    int offset = 0;
    int numRead = 0;
 
    InputStream is = new FileInputStream(file);
    try
    {
      do {
        offset += numRead;
 
        if (offset >= bytes.length)
          break;
      }
      while (
        (numRead = is
        .read(bytes, offset, bytes.length - offset)) >= 0);
    }
    finally
    {
      is.close();
    }
 
    if (offset < bytes.length) {
      throw new IOException("Could not completely read file " + file.getName());
    }
    return bytes;
  }
