I've attached a document that I made last week. It's (currently) an lmtx only
feature. In acrobat, the 'marked' areas (some tracing option) are the
hyperlink. I have no clue how useful this is, maybe for maps or some
educational setting. I had it on my agenda to play with it anyway. I don't
think that viewers other than acrobat support it (even if it's already quite
old pdf stuff; they should anyway fall back on the rectangle) but who knows ...
I only tested sumatra (the okular that I have doesn't even seem to handle the
links at all). It's not really efficient in bytes because it's (I think) meant
for another usage. As with more features in the pdf format I think it might
have started as some hack, but it's documented so ...
Hi Hans,
I tested Preview.app, Acrobat Reader DC, Acrobat Pro 9, PDF Studio Pro 2019,
Foxit Reader and Skim on macOS Mojave.
Sumatra (mupdf) also doesn't support it.
The masked or non-rectangular link areas works only in Acrobat Reader and Pro.
The others handle the links as whole page rectangles. Skim doesn’t always jump
to the right page.
I’ll send your example to the developers of PDF Studio.
Ok, thanks. Maybe we should have a wiki page that sums up viewers and
what they support.
Hans
