using prLink for internal links

[Mark Mitchell]

I'm trying to create links in a PDF that link to another page but I can't seem to find the correct URI scheme to accomplish this.

I've tried

 prLink( { page   => 2,

             x      => 190,

             y      => 95,

             width  => 230,

             height => 20,

             URI    => 'this.pageNum=1;'     } );

and also

 prLink( { page   => 2,

             x      => 190,

             y      => 95,

             width  => 230,

             height => 20,

             URI    => 'test.pdf#page=2;'     } );

This always creates links to external URLs. Is there anyway to add internal links to a PDF page?
