I just wanted to followup and say yes, this fixed it! What I didn't realize was the ColumnText was implicitely doing a beginText() and endText(). I changed all my showTextAligned with static calls to ColumnText.showTextAligned, and left most of hte 'block' section (because I need wrapped text for long names), and things are working perfectly. Thank you very much for your help! Here is the final / complete method, which still has the 'dotted line' around the block area, but that's just for testing, we'll remove that in the production print routine :) http://pastebin.stonekeep.com/11529 -d -- Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl ___ iText-questions mailing list iText-questions@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/itext-questions Many questions posted to this list can (and will) be answered with a reference to the iText book: http://www.itextpdf.com/book/ Please check the keywords list before you ask for examples: http://itextpdf.com/themes/keywords.php

[iText-questions] Problem adding ColumnText onto existing Document
Hi folks - i have a set of code that uses iText to place fields on a
form (in fact, it's a badge for a convention). The fields are laying
out in absolute positions on the document, but I want to add a block
that wraps text within the block (for a long badge name, for example).
The entire codeblock is posted here:
http://pastebin.stonekeep.com/11527
The boiled down version is this:
1) I create PdfContentByte 'cb' on a Document
2) Using lines like this, I place 'badge rows' (br) where i want them:
cb.showTextAligned(PdfContentByte.ALIGN_LEFT,printElement,br.getPosx(),br.getPosy(),0);
I have a cb.beginText(); and a cb.endText() around the entire logic.
This all works great until I try and place a 'block' item, which uses
this code:
logger.debug("Printing field " + fname + " using block layouts.");
// This first block simpley draws an 'X' across the field area I want to
use. This renders fine...
cb.setLineDash(6, 0);
cb.setLineWidth(1);
cb.moveTo(br.getPosx() - (br.getWidth() / 2),br.getPosy() -
(br.getHeight() / 2));
cb.lineTo(br.getPosx() + (br.getWidth() / 2),br.getPosy() +
(br.getHeight() / 2));
cb.moveTo(br.getPosx() + (br.getWidth() / 2),br.getPosy() -
(br.getHeight() / 2));
cb.lineTo(br.getPosx() - (br.getWidth() / 2),br.getPosy() +
(br.getHeight() / 2));
cb.stroke();
Font btFont = new Font(bf,br.getFontSize(),Font.NORMAL);
Phrase blockText = new Phrase(15,printElement,btFont);
ColumnText ct = new ColumnText(cb);
ct.setSimpleColumn(br.getPosx()-(br.getWidth() / 2),
br.getPosy()-(br.getHeight() / 2),
br.getPosx()+(br.getWidth() / 2),
br.getPosy()+(br.getHeight() / 2),
19,
Element.ALIGN_CENTER);
ct.addText(blockText);
ct.go();
If this code executes, all OTHER fields on the document disappear, and I
end up with just a few characters of the field, with the X through it,
and nothing else on the document.
What am I doing wrong?
Thanks...
