What does it matter if it's displayed in the document or in an overlay window or if it's saved in the document or not? That code could try to do anything; many PDF readers have a security option to prevent opening any remote documents or links.

Why do you think there is remote code execution? Without being familiar with that code (or evince code, which does the same thing) I can almost guarantee there is no such thing (what even would they be executing and why?).

How is the remote reference rendered, other than by executing a renderer for that format in a window? Renderers for web pages, for example, are very powerful platforms with a long history of security issues.

Actually SumatraPDF is using MuPDF now. But there is some limitation on rendering PDF and eBook files. For example, formatting PDF file or displaying Unicode characters in epub file.

Do you mind reporting those issues either to SumatraPDF at https://github.com/sumatrapdfreader/sumatrapdf/issues or directly to MuPDF at https://bugs.ghostscript.com/ if it also has the same issue? Thank you! There are many wonderfully weird PDFs and epubs out there, but we do our best to fix issues. :)

Thank you for reaching out. Please refer to the following issue list from SumatraPDF repo [1] [2]. Epub rendering issue like [3] [4].

What the hell is Adobe doing Probably supporting 100% of the PDF spec. plus addressing all those obscure feature requests that 6 companies in this one very niche industry really really need. Sumatra is fantastic and basically the only PDF reader I use on Windows, but it does have maybe 10% of the features Adobe acrobat has. It is however the 10% that that basically everybody needs.

(I wrote SumatraPDF). I agree that Adobe has more features than SumatraPDF. Not necessarily the PDF spec itself - SumatraPDF displays pretty much any PDF you throw at it, just way more options and stuff. And it's not exactly slow. I'm sure the core rendering of PDF pages is same or faster. It's just slow to start. Like very, very, sluggish slow. And it's very visible to users. I don't think it's the features that cau…

Thank you for responding and congratulations on the success of SumatraPDF, it seems well-deserved.

I will say that on older systems, Reader/Acrobat are not just slow at startup. I am writing this from a machine that has an i7-2600 and 16GB of DDR3 RAM. Reader is almost unusably slow. It's absurd.

Now where's that Mac port? /s

SumatraPDF does not acquire a file lock on the pdf. This is really useful if you're debugging a process that outputs a pdf and you want to see how the pdf refreshes. With other readers the tool that tries to replace the pdf will fail as the pdf viewer has a lock on the file.

I work in Health IT here in Germany and for the past 3 years we've been "testing" those "smaller companies" for different parts of our business. It's a mess. We've been paying them serious money for a product. We've never been warned that their product isn't finished yet or that we're the beta testers for the product they'll sell to other clients. Or that we have to invest our own personal and their time to fix their…

What "older and larger" company do you have in mind? What ever you do, never choose CGM! They wouldn't even be able to spell "test" if their live depended on it! Nothing new ever works, like at all. Everything older needs at least one or two server restarts a day!

medavis for example.

I know CGM from medico...their KIS is a nightmare. We have to communicate with it in hospitals. What an ugly monster and somehow no hospital IT is able to admin it properly.

The reference being discussed seems to be another part of the same pdf.

I think you've misunderstood the feature. It shows an overlay window of another part of the same PDF you're already in. It doesn't open another PDF or a website or anything, it's just a small preview of another page essentially. You could just as easily scroll to where the reference is placed in the PDF, but this lets you quickly preview the section without actually leaving your position in the document.

For extracting to tables I've been using http://tabula.technology/ for a couple of years. It seems to do a pretty good job even with some fairly complex tables and I've not had any problems with it.

you can also use okular for visually select a table from a pdf and paste it in sone excel kinda software and okulars table select tool is not too bad
