Problems with bookmarks not pointing to the right place

[vivadavid]

Hello,

I found this thread on the same subject (https://forum.pdf-xchange.com/ ... rks#p38578), but it’s old and I thought it would be better to create a new one as the problem, as far as I know, hasn’t been solved.

My problem concerning the bookmarks is that I select some text (the name of a chapter or a section), I click on Add Bookmark, the bookmark is created, but then when I’m on a particular page and I click on the bookmark, the programme doesn’t show the part of the page where the bookmark should point to (especially with a zoom like 175%, for example). In my particular case, I’m talking about a document in which every page consists of two pages of the original book. So if I’m reading, for example, a left page (an even page) and I click on a bookmark that should point to a right page (an odd page), the programme shows me the right PDF page, but it doesn’t go to the right side. It stays on the left side, which was the side I was reading before I clicked the bookmark.

Apart from that, I’d like to say that PDF X-change is an excellent programme. I love how fast it is, the possibility of having different styles on the reviewing tools, and many other things. I’ve been using Adobe Acrobat for a long time now and it’s hard to make the transition, but once this particular problem is sorted out, I think I’ll definitely move to PDF X-change.

Thank you for your help!!

Hello David,

And welcome to our forums.

I did check your file, and looking at the bookmark position - it is set to take you to a point 4.37 cm above the lower left corner of page1 in your document:


And this is exactly where our Viewer takes me when I click the bookmark.

Please note that if you are Viewing your document in single page mode in most zoom levels clicking the bookmark will show you the bottom of the page, and the topmost point in the page you can see will not be the bookmark location.

Best,
Stefan

Thank you for your answer, Stefan.

I don't know what happened with the file, but I'm sending the right one, where there is a bookmark pointing to a section on the right side of the second page. For some reason, when I try single page mode, it works, but I always use continuous mode anyway. The problem, which doesn't happen in Acrobat Reader, bothers me, as the main point of having bookmarks is to be able to click on them and go to the exact part of the age where it points to. Is there something wrong with my PDF? I wish a solution can be found, as I love many aspects of PDF Xchange and I would like use this programme with all my PDF files.

Again, thank your your help and congratulations on the good work.

Please check attached PDF file and screenshots.
As you can see there are two bookmarks: "Left" and "Right" which positioning second page of the document to show left or right part respectively.
For sure, to show only right part viewer's window should be able to scroll the page enough to hide left part.

Thanks.

I've checked your PDF, as this is what I get:

1. I am on page 1, right side. I click on Left and the programme shows page 2, left side, centered. No problem. SAME RESULT AS YOU.
1. I am on page 1, left side. I click on Right and the programme shows page 2, but only shows the right side partially (see attached file).

The ideal thing would be for PDF Xchange to always scroll left so that the viewer can read that column of text.

So can anything be done? Thank you.

The problem reproduced and fixed. The fix will be available in the next build of the viewer.

That's excellent news!! Thank you so much!

Also, now that we are talking about bookmarks, I was wondering (and I don't know if I should start a new thread), if it would be possible to allow PDF X-Change to do something. Let's say that I have a bookmark corresponding to page 30 and another to page 35. Later, I decide I need to create a bookmark on page 32, and so it would make sense to place the bookmark link between those two, following the page order. Unfortunately, that's not the case in the PDF programmes I've used so far, and the bookmark link is placed sometimes in the right position, but very often in a random one.

Thanks again!

New bookmark is added after currently selected bookmark. Then you can move it to any position you want to.

[vivadavid]

Although it's true that bookmarks can be moved on the list, wouldn't it be better if the programme could automatically place a new bookmark following page number and the position within the page?

Finally, I would like to report that under "Bookmark properties", the "Appearance options" are disabled and I can't change them.

Hello vivadavid,

While you are right that in most cases you will need the new bookmark to be placed in a position relative to the existing ones that corresponds to it's location in between the others it will not be possible for any program to guess the correct position 100% of the time as the bookmarks are a tree structure.

Imagine you have bookmarks arranged like this:
- a - pointing to page 1
- a.1 pointing to page 2
- c - not pointing anywhere, and just serving as a node so that c.2 and c.3 could be grouped together (yes unusual but not impossible)
- c.2 - pointing to page 6
- c.3 pointing to page 7

Now you want to place a new bookmark pointing to page 4 - how is the application to decide whether the new bookmark should be in position a.2 , b or c.1 - this is information which only you as the bookmark creator will have - so the manual editing of a new bookmark's position in my opinion is not something that could be avoided with any kind of prediction algorithms incorporated in the bookmarks creation process.

Best,
Stefan

Hi Stefan,

I am also very interested in this behavior as we've previously discussed https://forum.pdf-xchange.com/ ... 958#p47958. I understand that it's not possible to guess the correct position 100% of the time. But, that doesn't seem to me like a big problem.

For an easy solution, position b could be selected every time. After inserting several, the new bookmarks could be shifted as a group into the correct position.

For an improved solution, I could imagine using the expansion information from a and c. In other words, use a.2 if a is expanded, and c.1 if c is expanded. In ambiguous cases such as a and c both expanded, I would go to the default b position.

I imagine there are other subtleties involved, but I don't think that should be an impediment. I think the easy solution above would be good enough, and the improved solution even better. My main problem is that I add a bunch of bookmarks that end up lost somewhere in the bookmark tree. At least, if they were in page order, it wouldn't be so difficult to find them.

Hello Peter,

The ticket I created in your topic (#972) is still active I believe (we are having some maintenance downtime of the ticketing system, so I will check again when it's back online) so yes the guys will have this into consideration.

Best,
Stefan
