I�m creating pdfs with header data coming from databases. Until now I have used a fixed header height and tableevents, this way headers can be tables with images and text. It works fine. However this is not enough for all cases. Header data sometimes is mixed with content.
To obtain the table height I first call writer.fitspage(oTable) and then oTable.getTotalHeight(), having this value I set document margins.
However totalheight value is different when called after document.add(oTable). The difference between the values is noticeable in the generated pdf file.
Is there any other way of getting a pdfptable height? It seems that the value obtained after document.add(table) is correct, but how can I get it? I need the height value before adding the table because document margins depend on the header's table height.
I include in this message the code that will recreate the situation. Sorry if you find the code lenghty but the problem with totalheight does not always show up.
The first red line should be closer to the upper row with yellow background. I am using itext 1.00.
By the way value obtain during pageEvents after fitspage() is different from value obtained after fitspage() in main().
Thanks in advance, Rolando.
