Looks like if we want to add Head or Foot for the page. we need to pointed the html page file address, for example :
new ObjectSettings { header.htmlUrl= "c:\head.html"};
new ObjectSettings { header.htmlUrl= "c:\foot.html"};
But could we directly use html content for instant? for example :
new ObjectSettings { HeadText = "<html><body><div>This is head</div></body</html>" }
new ObjectSettings { FootText = "<h1><html><body><div>This is foot</div></body</html></p>" }
