Nope, still the same mistake.
And about the right wall/left wall coordinates: how does the left/right
wall coordinates should be specified? the javadoc is not really clear
about that:
*---
setColumns*(float[] leftLine,
float[] rightLine)
"Sets the columns bounds. Each column bound is described by a |float[]|
with the line points [x1,y1,x2,y2,...]. The array must have at least 4
elements."

You are missing ct.setYLine(20). If you are doing irregular columns it's
advisable to also draw the walls (moveTo/lineTo) as a first debugging
step. You may have the right wall at the left of the left wall.

Hi,
I'm kind of stuck with this problem: the document I'm doing has a
pretty complex form so I would really would like to
specify Polygon
(instead of Rectangle) for the form of the SimpleCell (which would
look like this: http://ilja.webmedia.ee/cell.gif ). Is it
possible at
all? Or is there some clever hack for achieving the same result?
See http://itextdocs.lowagie.com/tutorial/objects/columns/
look for the word irregular.

Hello, Bruno,
thanks for your reply, but it seems I'm too dumb to understand how it
should work. For instance, why wouldn't the following
proof-of-concept work?
----
Document document = new Document();
try {
PdfWriter writer = PdfWriter.getInstance(document, out);
document.open();
PdfContentByte cb = writer.getDirectContent();
ColumnText ct = new ColumnText(cb);
float[] left = {10, 10, 20, 20};
float[] right = {0, 0, 30, 30};
ct.addText(new Phrase("bla-bla bla-bla-bla-bla
bla-bla bla-bla
foo!\n", FontFactory.getFont(FontFactory.HELVETICA, 12)));
ct.setColumns(left, right);
ct.go();
}
catch(DocumentException de) {
System.err.println(de.getMessage());
}
catch(IOException ioe) {
System.err.println(ioe.getMessage());
}
document.close();
----
The compiler says that
ExceptionConverter: java.io.IOException: The document has no pages.
at com.lowagie.text.pdf.PdfPages.writePageTree(PdfPages.java:119)
at com.lowagie.text.pdf.PdfWriter.close(PdfWriter.java:1180)
at com.lowagie.text.pdf.PdfDocument.close(PdfDocument.java:934)
at com.lowagie.text.Document.close(Document.java:500)
But why? Shouldn't the ct.go() flush the output to pdf?
Unfortunately,
I'm no export on pdf format so the last sentence could very well be
stupid :)
Cheers,
Ilja
