Re: How can I keep text from interfering with linedrawings/shapes?

private void AddText(iTextSharp.text.Font iFont, float ptLeft, float ptTop, float ptHeight, float ptWidth, int alignment, string toPrint)

Subject: [iText-questions] How can I keep text from interfering with
linedrawings/shapes?



Using iTextSharp, I am creating PDFs of absolutely positioned text
(SetSimpleColumn) and lines.  It seems that the text is shifting the
position of some lines.  When I remove all of the text, the lines return to
their proper location.  This is unexpected behavior.

I've tried using DirectContentUnder to draw the lines under the text, but
this doesn't seem to have any real effect - except that the text does appear
over the lines.

How can I draw lines that will not move or shift position with regards to
text?

Thank you in advance for any help you can offer.

JG
