Paulo, I asked the developer of Leptonica/Jbig2 software for the problem that jbig2 compression loses the orientation. They fixed it and now the image with orientation tag = 8 comes to iText already rotated - and setRotationDegrees is not necessary any more. The setPageSize(PageSize.A4.rotate()) is now sufficient to show the page with the proper orientation in pdf.
Thanks a lot for everything ! Giuseppe. Ps. I have been surprised on how easy has bee to include a multipage jbig2 stream and symbol table with iText ....
