            Description

            Recently we've been seeing quite a few malformed PDF documents generated with iText. In this particular case the CCITTFax image is encoded with the wrong K value and as a result we don't decode the image using the correct algorithm.

              ICEsoft Public SVN Repository #23753 Mon Jan 10 07:48:03 MST 2011 patrick.corless PDF-249 added fall back code to the ccittfax k value algorithm selection code. If an error occurs during decode the exception is caught and the T6 algorithm is used to decode the image as a last resort. This address some iText mailformed PDFs.
