Hi Everyone, After searching so many hours (10h, 12h ?? api too complex for me ?) , to solve my problem of "merging" my report i've finally found a solution.
I found this page on the internet : http://stackoverflow.com/questions/9517719/how-can-i-stitch-two-pdf-pages-together-with-pdfbox-java The code can also be found in TestLayerUtility ( http://svn.apache.org/repos/asf/pdfbox/trunk/pdfbox/src/test/java/org/apache/pdfbox/util/TestLayerUtility.java ) So i modified my report to separate recto from the verso : Original has Dispositions : Recto1 Verso1 Recto2 Verso2 ... Even disposition : Recto1 Recto2 ... Odd Disposition : Verso1 Verso2 ... Final : Recto1(Rotate180)+Verso1 Recto2(Rotate180)+Verso2 I've to do this on the final document because i want to be able to fold the paper in 2 parts, then 3 parts for doing a paper-card. With PdfBox 1.7.1, when i open the document, the document is well produced but there is an "Acrobat error" at the openning. With PdfBox 1.6.0, all is OK. Can someone confirm this ? it seems that PdfBox 1.7.1 has a bug with layer ; i've joined the code below. For the developers of pdfbox, i think that you shoud add an example showing how to use layers more in depth ; it will be very appreciated.
