Subject Re: stamp annotation in pdf page 270 degree rotation incorrectly disdplayed
Date Sun, 14 Jan 2018 11:56:29 GMT
I looked at the file AnnotationSample.Standard.pdf (google for it) and 
it has many stamps... They do also have the problem with the "X" except 
on standard stamps.

I saw a "Rotate" entry in the dictionaries. Changing it changes the 
handle. This must be something non standard, i.e. for Adobe only.

stampAnnot.getCOSObject().setItem(COSName.ROTATE, COSInteger.get(270));
