It's fairly easy to "cheat" with AffineTransform. AffineTransform trans = AffineTransform.getRotateInstance( // I think the 360 - rot is right... not entirely sure Math.toRadians(360 - pagesRotation) ); double matrix[] = double[6]; trans.getMatrix(matrix);
content.concatCTM( (float)matrix[0], (float)matrix[1], (float)matrix[2], (float)matrix[3], (float)matrix[4], (float)matrix[5] ); I think there's now a PdfContentByte.concatCTM override that takes an AffineTransform directly, but that might only be in the post-5.x world... I don't recall when I added it. --Mark Storer Senior Software Engineer Cardiff.com import legalese.Disclaimer; Disclaimer<Cardiff> DisCard = null; > -----Original Message----- > From: RivasAviles, Miguel [mailto:miguel.rivasavi...@fwisd.org] > Sent: Thursday, May 20, 2010 4:25 PM > To: Post all your questions about iText here > Subject: Re: [iText-questions] Document rotates while merging > > Thank you Eric for pointing me on the right direction. > > I put couple of hours with the approach you told me and was able to rotate > the page (270) but now I have it upside down. > > But looking for more answers on the web seems to me like I opened a > pandora's box... people getting angry when talking about that matrix... > I'm even scare to ask about it :) > > Any ways thank you for your answer.
