Subject AW: Re: Adjust signature field for rotated pages
Date Mon, 29 Oct 2018 08:09:47 GMT
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.

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?

Thanks again and best regards

Patrick Herber
