[poppler] Clarification request: Several link actions in one position

[Leonard Rosenthol]

Always happy to help.

The order of the Annotations in the Annots array in the page dictionary defines the order in which rendering and hit testing is performed.   However, there is nothing that precludes you doing what you're doing with the multiple click choices as well.

    Dear Leonard,

    please allow me to ask about a detail of the PDF spec.  In

       https://nam04.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugs.kde.org%2Fshow_bug.cgi%3Fid%3D429635&data=04%7C01%7Clrosenth%40adobe.com%7C5f62d976c0e24b387a9208d8a001dbc6%7Cfa7b1b5a7b34438794aed2c178decee1%7C0%7C1%7C637435277147494112%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C1000&sdata=fj64FdUtAU6NGI2oTS%2BdXr4KFFS7lVR7UE2%2FEKVy4uk%3D&reserved=0

    we have received a pdf document with two link actions in the
    very same position.  Unfortunately, the spec doesn't seem
    to say what to do in this case.  Treat only the first one?
    Treat them all (somehow)?  In this particular case, one of
    the actions is practically empty and could be filtered out,
    but it is easy to imagine files with more than one nontrivial
    link actions in one position.  What should a conforming
    reader do?

    Thank you for your help!

    Best regards,
    Oliver
