I have accomplished this for my purposes using the ColumnText class rather
than a paragraph class. See the following function. (This is vb.net, and
strictly speaking it uses the J# port iText.net, not the original iText;
and even worse, I've wrapped some of the details into one of my own classes
called iTextPDF. But perhaps you can gain some insight anyway.)
Sub DoTextBox(ByVal oPDF As iTextPDF, _
ByVal strOverflowFile As String, _
ByVal strText As String)
' Create a ColumnText object,
' assigned to the ContentOver stream of our pdf
Dim ct As New ColumnText(oPDF.cbOver)
' Create a font to use
Dim bf As BaseFont = BaseFont.createFont(BaseFont.TIMES_ROMAN, _
BaseFont.CP1252, BaseFont.NOT_EMBEDDED)
' Add text to the ColumnText.
ct.addText(New Phrase(strText, New Font(bf, 12, 0)))
' set the first-line indent to zero, and following lines to 9 pts.
ct.Indent = (0)
ct.FollowingIndent = (9)
' setSimpleColumn sets up what we need. This is a single column
' with the bounding box taken from the wrapper object,
' a height of three inches, 16 pt leading, and left aligned text
ct.setSimpleColumn(oPDF.left, oPDF.bottom, oPDF.right, 3 * 72, _
16, Element.ALIGN_LEFT)
' the rest of this fills the text to the box we wanted, overflowing
' to additional pages if necessary.
' "continued on" and "continued from" lines to the overflows.
Dim status As Integer
status = ct.go()
Do Until status = ct.NO_MORE_TEXT
oPDF.newPage()
ct.setSimpleColumn(oPDF.left, oPDF.bottom, oPDF.right, _
oPDF.top - 16, 16, Element.ALIGN_LEFT)
status = ct.go()
Loop
End Sub
