How do I specify the word spacing, text justification?

Q: Is there a way within PDFtron to specify the word space size?
We need it so we can justify our text.

I am looking at the PDF text state operators and I am not sure you
support them.
Can you let me know what font text state operators you support?

A: How about using element.GetGState().SetWordSpacing(num)?
For more info, please refer to the API Reference Manual:
  http://www.pdftron.com/net/html/classpdftron_1_1PDF_1_1GState.html
  Javadoc: http://www.pdftron.com/net/Javadoc/pdftron/PDF/GState.html

PDFNet supports all allowed text and graphics state operators in PDF.

Regarding text justification (e.g. left/right/center) you may want to
refer to the following PDFNet KB article:
