Understanding PDPageXYZDestination.setTop(...)
Hello ,
I am trying to use PDPageXYZDestination to create an internal link that
could move to a specific area in another page in the same PDF. Here is the
code I've tried:
List<PDAnnotation> annotations = page1.getAnnotations();
PDPageXYZDestination dest = new PDPageXYZDestination();
dest.setPage( page3 );
dest.setZoom( 3 );
dest.setLeft( 200 );
dest.setTop( 200 ); // Does nothing at any value!!
txtLink.setDestination(dest);
annotations.add( txtLink );
When opening the output PDF using Adobe Reader and clicking the link it
takes me to page 3, zooms in to 300% and moves the viewable area 200 points
in X direction, so dest.setLeft( 200 ) works just fine, but for the Y
direction it keeps showing the top rectangle of page 3 whatever value I try
to use for dest.setTop( . ).
Do you understand PDPageXYZDestination.setTop( . ) wrong, or there is a bug
with it?
Best regards,
Hesham

Tilman,
I have tried it now and it's working. I must have been doing something wrong.
Thanks a lot 😊
Best regards,
Hesham

I tried it with the AddAnnotations example. There is a difference between 100 and 500. You can see the difference by looking at the scroll bar.
