Hi Roger!
When you're creating a new document. QuickPDF assumes that there should be at least one page - so QP does this automatically and so page 1 is already there. When you're adding now page by page to the new document i can imagine that you forgot the first page from QP? ... And so the index is shifted by one. Am i right?
Cheers, Ingo

the pdf is already in existence
i am just adding extra bookmarks to the pdf
the pdf has 20 bookmarks in it before i add extra bookmarks
the extra bookmarks point to the correct pages when viewed in adobe
BUT when i click on them they point to the page ABOVE the correct page
eg page 5 bookmarks points to page 6 after being clicked in adove

i have worked out that the problem is caused by the vertical position
if i set a position of 450 or greater, then the correct page appears
i am using setorigin top left
WHY DOES THIS HAPPEN ???

Hi Roger,
You have correctly identified the cause of the problem by setting the
vertical position to something other than zero. The default
co-ordinate system measures from the bottom of the page. So if a value
of 0 for the vertical position is used Acrobat / Adobe Reader will
show the next page (the top of the following page is attached to the
bottom of the linked to page).
I hope this helps.
Cheers,
Rowan
