Problem with annotation

Question

I have a plugin (developed in C++) to add stamps in a pdf. This plugin is based on the Stamper sample included in Acrobat 8 SDK. The plugin works well when adding stamps on a pdf page that is not rotated, but when the page is rotated the stamp rotates as well.
I don't want the stamp to rotate with the page, so I tried to set the annotation flag to 'No rotate' as follows:     PDAnnotSetFlags(annot,pdAnnotNoRotate);
but it doesn't work.
Does anyone have an idea about how to solve this?.
Thanks in advance,

Answer 1

I know how to get the page's rotation (pdPage = AVPageViewGetPage(pageView);
pdRotate = PDPageGetRotate(pdPage)
but I don't know how to rotate the stamp. Could you tell me how to do it?
This is part of my code.
Thanks,
