Hi, please share the signed 90° file (upload to a sharehoster, attachments are usually deleted). I'll have a look at it with PDFDebugger to see what is different.
Tilman --- Original-Nachricht --- Von: Patrick Herber Betreff: Re: Adjust signature field for rotated pages Datum: 29.10.2018, 8:02 Uhr An: [email protected] Dear Tilman Thanks a lot for your reply I’ve tried with the “latest" snapshot WAR files of version 2.0.13 (2.0.13-20181024.204010-80), 2.1.0 and 3 (3.0.0-20181026.180346-919) using the trunk version of the CreateVisibleSignature example class, changing only the line you mentioned inside the setVisibleSignDesigner method but unfortunately with all these versions I get the same result as in my previous screenshot: the width of the image is not correct. After the adjustForRotation() call the value of affineTransform is as you wrote: AffineTransform[[0.0, -2.88043475151062, 265.0], [0.347169816493988, 0.0, 0.0]] What could be then the difference?
