How do I place text to PDF using ElementBuilder & ElementWriter?

Q: I would like to import some test from a '.txt' to a target PDF.
Ideally I would like to use ElementBuilder and ElementWriter so that I
have full control over text layout. Do you have any relevant sample
code?

Aside: Is PDFNet thread safe?

A: PDFNet SDK is fully thread safe (http://www.pdftron.com/net/
faq.html#can_server).

As a starting point to get familiar with ElementBuilder and
ElementWriter you may want to take a look at ElementBuilder sample
project:
  http://www.pdftron.com/net/samplecode.html#ElementBuilder.

Also, for an example of how to output a column of text (imported from
a test file), you may want to take a look at Text2PDF.zip in the
'Files' section of this forum (http://groups.google.com/group/pdfnet-
sdk/files). Simply extract the sample under 'PDFNet\Samples' and run
it without any modifications.
