1. Re: creating polygonal links in PDF

You can create an arbitrary quadrilateral shape to associate with your link. You can have as many of them as you'd like.
The idea of more flexible shapes for Links has been discussed over the years but not made the standard.

2. Re: creating polygonal links in PDF
user01pp Mar 7, 2014 12:57 PM (in response to A. Grahn)Does this mean that you could create a link annotaion region that appears as a rotated rectangle for example? Say I wanted a hyperlink region to cover a URL that is part of a raster image within the PDF. The URL appears at a 30 deg rotation on the page. Is this something that can be done in Acrobat Pro? It seems that the link tool in Acrobat Pro can only create 0 degree link regions.

lrosenth Mar 9, 2014 9:57 AM (in response to user01pp)The PDF file format allows for rotated links using the QuadPoints key (ISO 32000-1:2008, 12.5.6.5) but you are correct that Acrobat's UI doesn't provide authoring of this.
