[iText-questions] PdfPCell aligning to baseline rather than bottom of font?

[Frederik MJ Sauer]

While not really noticable at smaller font sizes, it appears that 
PdfPCell is placing it's phrase in such a way that roughly the baseline 
of the bottom is at the bottom of the cell, causing the lower part of of 
characters that drop below the line (e.g. pyj,qg) to cross over the 
bottom border of the cell. See, for example, the letter "g" in the word 
"Testing" as the font size increases in this example:

 PdfPTable ptable = new PdfPTable(1);
 ptable.getDefaultCell().setBorderColor(Color.RED);
 ptable.getDefaultCell().setBorder(Rectangle.BOX);
 ptable.getDefaultCell().setBorderWidth(.1f);
 ptable.addCell(new Phrase("Testing", 
FontFactory.getFont(FontFactory.COURIER, 7f)));
 ptable.addCell(new Phrase("Testing", 
FontFactory.getFont(FontFactory.COURIER, 10f)));
 ptable.addCell(new Phrase("Testing", 
FontFactory.getFont(FontFactory.COURIER, 20f)));
 ptable.addCell(new Phrase("Testing", 
FontFactory.getFont(FontFactory.COURIER, 30f)));
 ptable.addCell(new Phrase("Testing", 
FontFactory.getFont(FontFactory.COURIER, 40f)));

 document.add(ptable);

In examples/Chap0518.java it appears that a small font size and 
datatable.getDefaultCell().setPadding(3) are used. Certainly a padding 
can be used to prevent the lower part of the letters dropping through 
the bottom of the cell, but one must (re)adjust the padding based on the 
font size, and as the font size increases, the amount of 'extra' padding 
between the top of the phrase and the top border of the cell increases.

If this is not by design, could you point me to the section of code I 
can look at to fix this?

Keep up the good work, and thanks for the quick responses!

Fred
