links and scroll position
Hi,
i would like to create a bookmark which scrolls to a position within the pdf. For that purpose I've tried to use a PDPageXYZDestination, which
comes with a setTop method.
Does anyone know, how setTop works in combination with and without page.Rotation and what exactly should be the behavior ?
I would like to have similar scroll behavior like in web webbrowsers, right now it seems to only scroll to the correct page.
The Acrobat Pdf Reader shows different sroll behaviours if I click on the bookmarks. I guess it depends on the zoom and display resolution, if a complete page
fits into a screen or not?
final PDPageXYZDestination dest = new PDPageXYZDestination();
dest.setTop((int) ?); // is this value befor rotation , after rotation ?
PDOutlineItem pdOutlineItem = new PDOutlineItem();
pdOutlineItem.setDestination(dest);
best regards,
david

Re: links and scroll position
Posted by Tilman Hausherr <TH...@t-online.de>.
The PDF specification just tells "All coordinate values (left, right,
top, and bottom) shall be expressed in the default user space coordinate
system." Why not just try it? It won't bite.
An example on the use of PDPageXYZDestination can be found here, not
related to bookmarks:
