Thanks for all the tips!

Yes, option 2 was what I meant.
You can increase the page size.
It's done more or less like this: http://1t3xt.be/?X0003df
But instead of the PdfName.CROPBOX, you change the PdfName.MEDIABOX.
Also you can use negative values for the rectangle.
For instance: new PdfRectangle(0, -52, 612, 720);

I dont' think i want to run with this because a) the content will
still be in the bottom left corner of the page. I want flexibility
where i add the text: bottom left, bottom centre, bottom right, top
left, top centre, top right. So, to add the text to the bottom of the
page I'd have to translate the content anyway, using a template or
appending a cm. I don't see how shrinking the rectangle is going to
help me at this stage.

I think that is actually what I want. None of the pdfs I'll be dealing
with will have any interactive content. If I do actually come across
such pdfs I can write code to move all of the interactive content.
Also, I would like to change the content as little as possible in this
resizing process.
I'm happy to do this on my own but do you have any useful references
in the pdf reference? The section on content streams and resource
dictionaries is pretty bare.

You're probably removing the XObject with the content.
I should see an example to know for sure.

It would be great if you could help me with the disappearing page
content problem. My workaround for this issue creates 3 pdfs in total.
This makes a fair performance hit when processing very large pdfs.
This is my code:
Private Function StampPages() As Boolean
Dim dictDestPage As PdfDictionary
Dim dimens As Hashtable = New Hashtable(4)
For Each page As PDFStamperSettings.PageSetting In
StampSettings.PageSettings
Dim current As Integer = NumberOfPages + page.IndexInParent
page.Size = newPDFReader.GetPageSize(page.Number)
page.Rotate = newPDFReader.GetPageRotation(page.Number)
'Add a page to the new pdf
newPDFStamper.InsertPage(current, page.Size)
Dim srcPage As PdfImportedPage =
newPDFStamper.GetImportedPage(newPDFReader, page.Number)
'Get the content of the PDF under the current content
Dim destUnderContent As PdfContentByte =
newPDFStamper.GetUnderContent(current)
'Set the boundaries of the stamps
page.SetBounds()
'Determine the dimensions of the new template
dimens = generate_dimensions(page, page.Width, page.Height)
'Add the extracted page as a template
destUnderContent.AddTemplate(srcPage, dimens("xScale"), 0, 0, _
dimens("yScale"), dimens("xDiff"), dimens("yDiff"))
For i As Integer = 0 To (page.Stamps.Count - 1)
If TypeOf page.Stamps(i) Is StampText Then
Dim stamp As StampText = page.Stamps(i)
'Start adding text
destUnderContent.BeginText()
'Set the font fize, set the position (matrix) and
add the text (showtext)
destUnderContent.SetFontAndSize(stamp.Font, stamp.FontSize)
set_text_position(stamp, destUnderContent,
page.Width, page.Height)
destUnderContent.ShowText(stamp.Text)
'Stop adding text
destUnderContent.EndText()
ElseIf TypeOf page.Stamps(i) Is StampLine Then
Dim stamp As StampLine = page.Stamps(i)
'Set the start and end point of the line
set_line_position(stamp, destUnderContent,
page.Width, page.Height)
'Draw the line
destUnderContent.Stroke()
End If
Next
'Extract the PDFDictionary of the destination page and
'add a Rotate PDFName for rotating the document
dictDestPage = newPDFReader.GetPageN(current)
dictDestPage.Put(PdfName.ROTATE, New PdfNumber(page.Rotate))
'Stop the document from auto-correcting the rotation
newPDFStamper.RotateContents = False
Next
Return True
End Function
Private Function RemoveAndReplacePages() As Boolean
'Remove/replace unwanted pages
If NumberOfPages = StampSettings.PageSettings.Length Then
'All old pages removed
'Create a pageRange in the format of "1-9,15,23-45"
'Selects a range from the old number of pages plus 1
(where the new pages start) to the end of the pdf
pageRange = (NumberOfPages + 1).ToString() + "-" +
(NumberOfPages * 2).ToString()
'Keep only those pages within the selected page range
newPDFReader.SelectPages(pageRange)
Else
'Select pages to replace
Dim newPDFReader2 As PdfReader = New PdfReader(PDFFile + ".tmp")
For Each page As PdfStamperSettings.PageSetting In
StampSettings.PageSettings
newPDFStamper.ReplacePage(newPDFReader2, NumberOfPages
+ page.IndexInParent, page.Number)
Next
newPDFReader.SelectPages("1-" + NumberOfPages.ToString())
newPDFReader2.Close()
End If
'close and clear the streams
Close()
Return True
End Function
Thanks heaps.
Cheers,
Billy
