To get the content stream, you can do any number of things:
1) Breakpoints in the debugger/hack PdfContentByte to call System.out
when writing itself.
2) RUPS, a part of iText. It's a PDF object browser UI built on iText.
Quite Handy.
3) A commercial/free trial acrobat plugin by the name of PDF Canopener,
by... Windjack Solutions Inc. No affiliation. I have a less "feature
rich" version built internally way back in... 98? 99? Something like
that. Still works fine. Hurray for backward compatibility... (and that
might explain why there's no 64-bit Acrobat)

Heh, I like the way you guys think! But how the heck are you
seeing that text? What I see is compressed.
Anyway, I first tried an idea stemmed from the other email and
assigned the font in use to the chunk that is containing the
DottedLineSeperator. Hoping that would give it the proper glyph spacing.
While when viewed in pitstop I did notice that the selection of
the page number text does now correlate with where the text is viewed
at. However, it did not fix the problem with using other versions or
rips.
Next I tried the white dot trick below, that didn't seem to do
it either. But the method calls used were a little different than below
but I am just guessing that is due to the .net port being slightly
different in it's naming.
I updated from 5.0.2 to 5.0.5 and created this quick test run
below and get the attached resulting output (yeah yeah , I know, it's
VB. Sorry).
Current;y as a work around I am doing a method that uses
getWidthPoint on three chunks while increment the middle one in a loop
until the full width is correct and then drawing the line on the middle
one as a generic tag. Not as pretty looking and it really slows the
process down when it gets to the index at the back of the book. Oh well.
I do appreciate the help though. I think you guys know the
internals of PDF's better than Adobe :-)
Sub Main()
Dim d As New Document
Dim w As PdfWriter = PdfWriter.GetInstance(d, New
FileStream("c:\DottedLineSeperatorTest.pdf", FileMode.Create))
d.Open()
w.Open()
With w.DirectContent
.SaveState()
.BeginText()
.SetFontAndSize(BaseFont.CreateFont, 1)
.SetColorFill(BaseColor.WHITE)
.ShowText(".")
.EndText()
.RestoreState()
End With
Dim f As Font = FontFactory.GetFont(BaseFont.HELVETICA,
12)
For i As Integer = 1 To 30
Dim p As New Paragraph("line " & i, f)
Dim c As New Chunk(New
iTextSharp.text.pdf.draw.DottedLineSeparator)
c.Font = f
p.Add(c)
p.Add(New Chunk(i, f))
d.Add(p)
Next
d.Close()
w.Close()
End Sub

Re: [iText-questions] Help with DottedLineSeperator.
Okay, here's some of the relevant content stream from
"toc_sample_ok"
BT - begin text
36 751 Td - move to the start of the next line with the
given offsets
0 -16 Td - err... okay.
/F6 12 Tf - 12 point, font resource "F6"
(Additional Benefits Contact List)Tj - display the given
text
/F9 12 Tf - 12 point, font resource F9
[-31165]TJ - use kerning to adjust the location of the
text a whole bunch
/F6 12 Tf - 12 point, font F6
(9)Tj - display the given text.
0 0 Td - move to the start...
0 -16 Td - move to the start...
Okay. That's funky, but it works. Ish. And here's the
"optimized" version:
BT
/T1_0 12 Tf - they change the font resource name. No
big deal.
0 Tc 0 Tw 0 Ts 100 Tz 0 Tr 36 735 Td - set a bunch of
defaults
(Additional Benefits Contact List9)Tj - never
switched to the other font, never adjusted kerning. Oops.
0 -16 TD
- next line, with a tweak
(National Contracted Facility/Vendors10)Tj - ditto, never
switched fonts, never adjusted kerning.
I suspect that becuase F9 is never used to draw anything,
"optimization" throws it out and (erroneously) eats its kerning info.
That's a good theory, and I'd wager a beer on it, but it really doesn't
help us to solve the problem... OR DOES IT?! Okay, ugly hack time.
F9 happens to be helvetica. You need to draw something,
ANYTHING, with that font. Draw a background-colored period at 0,0...
whatever. In doing so, you'll force the optimizer to not discard that
font, hopefully preserving the kerning info and keeping your text where
it belongs:
PdfContentByte cb = writer.getDirectContent();
cb.saveState(); // don't change anything that comes after our
little hack job here
cb.beginText();
cb.setFontAndSize( BaseFont.CreateFont(), 1 ); // the default
CreateFont returns winAnsi Helvetica, convenient.
cb.setFillColor( Color.WHITE );
cb.drawText('."); // " " might work too, but an overly clever
optimizer might remove it.
cb.endText();
cb.restoreState(); // clean up our mess. For every saveState,
you MUST have a restoreState()

Sure thing,
The attachment toc_sample_ok.pdf views fine for me in using
Acrobat 7. It does not view fine in 5. Other people see different things
depending on their version but I don't have a comprehensive list as to
how each version reacts.
The second attachment, toc_sample_optimized.pdf, is the result
of optimizing in Acrobat 7. Seems to only get effected like this if the
option 'Convert smooth lines to curves' is selected. However, it is
similar to how other versions view with the two texts concatenated as if
there is no dotted line. Also, as I mentioned before, some versions (as
well as the Rip's on press) view with the page number text at about a
half way point.
I do notice when trying to select the page numbers in
toc_sample_ok.pdf using Ptistop that they are actually coordinated next
to the listing text but somehow transformed(?) to be viewed over toward
the right.

Subject: [iText-questions] Help with DottedLineSeperator.
Hi,
I am using the DottedLineSeperator to build a table of contents
(.net version). The result looks fine in Acrobat 7. It also prints file
if direct from Acrobat 7.
However, if viewed in other versions, ripped on the printer, or
optimized from 7 the page number loose their position. Sometimes the are
butted up against the left hand text. Other times the are somewhere in
the middle of the line.
Any hints? Below is the basic code that I am using.
Private Shared Sub ToDocument(ByVal ti As TOCItem, ByVal d As
Document, ByVal f As Font, ByVal level As Integer)
If Not ti.Ignore Then
Dim p As New Paragraph
p.IndentationLeft = level * 20
p.Add(New Phrase(ti.Value, f))
p.Add(New Chunk(New
iTextSharp.text.pdf.draw.DottedLineSeparator))
p.Add(New Chunk(ti.PageNumber, f))
d.Add(p)
level += 1
End If
For Each k As String In ti.SubItems.Keys
TOCItem.ToDocument(ti.SubItems(k), d, f, level)
Next
End
