I just found the announcement of iText 2.0.0, with following text in the release notes:
* iText and SEAM:
iText is now being used in jBoss SEAM, and after informing with Norman Richards
(who developed the PDF package in SEAM) I added some methods to iText:
o A helper method for jBoss SEAM:
convert a String with entities to a normal string
(with unicode characters)
o ElementTags: You can now convert an alignment String to an alignment value
o PageSize: there's a method in the toolbox that translates a String to a Rectangle,
but I rewrote a method by Norman Richards that has more potential.
My method could only translate Strings like "A4" and "LETTER"
to a corresponding Rectangle; with Norman's method you can
also use Strings like "400 600".
I adapted the method so that "166.66 333.33" are also allowed.
