I was asked about the new way to work with NFOP to generate the pdf without
the old Engine class. So here is what I am doing:

40 driver.run();
41 output.close();

43 int sz = output.buf.Length;
44 byte[] pdf = new byte[sz];
45 for (int i = 0; i < sz; i++)
46 pdf[i] = (byte) output.buf[i];

58 catch (FOPException fope)
