Hi Hans, many thanks for your reply. I’m afraid there might be something wrong with this. I have been using poppler-glib-demo to check it (and this is the first time I use it, so I might be wrong as well). The minimal sample: \enabletrackers[*destinations*] \setupinteraction[state=start, focus=standard] \setupinteractionscreen[width=fit] \starttext \completecontent \chapter{Chapter} \stoptext Link destination for “Chapter” seems to be: << /D [27 0 R /XYZ 70.867 689.409 null]>> But both chapter headings are placed at x,y (70.87, 122.22), according to poppler-glib-demo. Anyway, there is a proof that something might be rotten, because the link itself has a higher box (an it is lower in the page): << /Subtype /Link /Dest (#2) /F 4 /Rect [70.867 652.344 496.06 666.772] /Border [0 0 0]>> I cannot give a more accurate description (the PDF spec is all Greek to me), but I think there is something wrong with link destinations (they seem to be lower than they should be). BTW, does the sample above work right with Adobe? (I’m don’t have it installed.) It doesn’t work with either evince-3.10.3 or mupdf-1.6.
I think this should be improved. And I guess it goes unnoticed, because after clicking on a link, the browser fits view to page.
this is also a bit browser dependent i think
I guess this is caused by the link destination syntax (section 12.3.2.2 of the PDF specification). Withouth specifying "focus=standard" in the sample above, the link is: << /Subtype /Link /Dest [13 0 R /Fit] /F 4 /Rect [70.867 652.344 496.06 666.772] /Border [0 0 0]>> /Fit specifies that the page should be so that its entire width and height are magnified enough so that they fit in the window. Having said that, I cannot see why it makes sense that ConTeXt generates documents with this default. I mean, the default paper size is A4, if the default behavior after cliciking on a link is to fit page height (or width in landscape), one needs a huge screen not to render the text unreadable. Sorry, but I cannot see the gain in this default. Would it be possible that the default would be the behaviour set by "focus=standard"? Could you consider both suggestions?
