Thanks for the info.
So you would always recommend writing a PdfPTable using writeSelectedRow, and not
adding it to the document?
I found out that I could get the required effect by setting the widthPercentage on the
table. It seems to us here, that what is going on, is that the meassurement of a
rowheight is correct, when widths set, and totalWidth of the table is set, but when
adding the table to the page the totalWidth is not honored, for that you need to
calculate the totalwidth as a width of the page, and set that too.
Seems a little non intuitive that I need to tell the table 3 times what the width is
(in my case at least, first all the columns, then the total : add all columns, then
the percentage of the table according to the page width).
But anyways I have a workaround.
The bug is not the rowheight, but that totalwidth is not honored when adding to a
document, it's only used for calculating rowheight and not for outputting the table?
In any case life would be easier if there was a method on the document that could do
that calculation (it's very easy, but I tend to like to do this in one place, and the
document seems fit to this task).
float pctWidth = document.getWidthPercentage(table.getTotalWidth);
table.setWidthPercentage(pctWidth);
And furthermore it would be nice if this was documented better, and saying that, I
would be happy to document some of this, and provide examples.
Thanks again Paulo, it's been a big help in our further use of the library.
Thanks,
NEKO

There's no bug. You are measuring the height with a width but creating the
final table with a different width. To see what's really happeneing change
the main() method to:
public static void main(String[] args) throws Exception {
System.out.println("Writing document...");
OutputStream outputStream = new FileOutputStream("c:\\reperror.pdf");
Document document = new Document(PageSize.A4, 50, 50, 50, 50);
PdfWriter writer = PdfWriter.getInstance(document, outputStream);
document.open();
PdfPTable pdfTable = new PdfPTable(new float[] {_rowLabelWidth, 4 *
_columnLabelWidth});
pdfTable.setTotalWidth(_rowLabelWidth + 4 * _columnLabelWidth);
PdfPTable rowLabels = createRowLabels();
PdfPTable cells = createCells();
pdfTable.addCell(newCell(rowLabels));
pdfTable.addCell(newCell(cells));
pdfTable.writeSelectedRows(0, -1, 50, 750,
writer.getDirectContent());
document.close();
System.out.println("Done!");
}
To have the required effect change:
private static float _rowLabelWidth = 100f;

Thanks Paulo.
Please tell me if I can help with more information?
I can reproduce this very simply (I've made a bug report on SourceForge,
with a simple example).
Thanks,
NEKO

Subject: [iText-questions] Problems with getRowHeight of PdfPTable
Hi,
Thank you for the very best PDF Library for Java.
I have come across a problem that is stopping me in my use of this.
It seems that PdfPTable is giving me back wrong heights when I cell
getRowHeight(int idx).
I've attached the code to reproduce this.
It seems that my vertical labels returns
28.0
28.0
16.0
28.0
16.0
16.0
When that should have been
28.0
16.0
16.0
16.0
16.0
16.0
According to the output in the PDF, and also if I hard code the heights,
this is what appears to be the right thing.
Please tell me if I'm doing anything wrong, or if there really is a bug?
Thanks,
NEKO
