From: Henning Hraban Ramm via ntg-context @ 2022-09-22 18:07 UTC (permalink / raw)
To: mailing list for ConTeXt users; +Cc: Henning Hraban Ramm
Hi all,
I compiled a kind of wishlist what we need or look for in a new or
enhanced open source PDF viewer, as discussed e.g. at the 2021 meeting.
https://wiki.contextgarden.net/PDF_viewer
I’d like to further the subject to find a developer (or a team) and make
this a reality. (Of course I’d be happy to have Michal on board!)
Feel free to enhance the wiki page or discuss here.
I suggest we’ll discuss funding in the context group board, but there
was also a discussion about fundraising at the 2022 meeting that I
didn’t follow – I think Paulo said he had experience in fundraising?
Hraban

I think that pdf.js (the Firefox PDF viewer) meets most of these requirements. There are a few requirements that it doesn't meet, but it's open source and written in JavaScript, so we should be able to add anything that's missing.

I just tried it and find that it has an interesting feature of caching rendered pages. Pages with complicated graphics (think MetaPost with hundreds of thousands of objects) get rendered pretty quickly, although one can see the very many objects being drawn the first time the page is displayed. Subsequently displays of these pages have no lag whatsoever.

You’re right, pdf.js is quite good, and it’s already used by a lot of projects (browsers, editor plugins etc.) – the latter also means that you often encounter old/buggy/limited versions. Unfortunately, Firefox doesn’t register itself as a PDF viewer (at least on MacOS), that means I can’t use it easily to open a PDF from the command line (e.g. in scripts). But anyway, that could shift our focus to add/enable features for pdf.js in TeX editors. >> - PDF 2.0 compatible > > It can open PDF 2.0 files, but I doubt that it supports every single > feature. I won’t expect every feature, there are too many. Actually I don’t know which features of PDF 2.0 Hans was missing in viewers. >> - proper color and transparency display (respect color profiles) > > It supports all of the PDF colour models/profiles for vectors, although > it ignores embedded colour profiles in images. > > https://github.com/mozilla/pdf.js/issues/2856 > > Regular RGB and CMYK stuff works fine though. That’s a problem if you prepare PDFs for printing. Apple’s PDF library (used e.g. in Preview.app, Skim, TeXshop) also does a bad job at it, as well as Sumatra and Chrome (according to the comments to that ticket). >> - limited JavaScript support (no modification, no file operations) > > Yes, although it is quite limited: > > https://blog.mozilla.org/attack-and-defense/2021/10/14/implementing-form-filling-and-accessibility-in-the-firefox-pdf-viewer/ Thank you for the link! What they write about the scope of JS in pdf.js sounds good; but presentation stuff like buttons (e.g. for OCG) is probably missing. I need to check the limits of forms in pdf.js; but Mozilla even implemented XFA (e.g. Qoppa didn’t). >> - update on file change (configurable) > > Not by default in Firefox.

There’s still no PDF viewer on Linux that can handle annotations well. (But even Acrobat Reader on MacOS frequently crashes on them; I’m using Foxit Reader for annotations, but the one for Linux is too old.) >> for development/debugging: >> - show metadata (incl.

I tested it with the eforms manual: http://mirrors.ctan.org/macros/latex/contrib/acrotex/doc/eformman.pdf and it seems to work fine for me. I've also used it to fill out a few government forms in the past and it's worked too.

I've got a 1.1GB document with 16000 pages, and Okular handles it just as fast as a 10 page document. Firefox at least manages to not crash when opening the document, which is better than most viewers. Okular is actually a pretty nice viewer in general. It's really fast, and it also seems to support most of these features. The tricky thing with it though is that I think that it would be much harder to modify compared to pdf.js. -- Max ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 13+ messages in thread

Hi Hraban, I know you wrote scripts, but here you have two links on how to set another PDF default viewer: https://discussions.apple.com/thread/7883441 https://www.igeeksblog.com/how-to-change-default-pdf-viewer-on-mac/ And to open PDF documents from scripts, once the default viewer is set, it seems that "open" is the right way to go (similar to "xdge-open" in Linux). >>> […] >>>> - JS for calculations I would love that JS worked fine in PDF.js.

Annotations may be part of a PDF viewer, but the problem is that in some projects they understand that the feature to add them is part of a PDF editor (so annotations won’t be added). I think this is what happened to annotations in Evince (but I may be wrong here). And I wonder whether PDF.js might take this approach.

The issue may be trickier than we thought (since fixing Firefox with Heros+LMTX is only part of the issue). Just as a personal note, I tend to avoid using Heros with LMTX, since resulting PDF documents may be displayed (poorly on screen) with Acrobat. I wonder whether this is related to common code for both Acrobat and Firefox (originally comming from https://lists.nongnu.org/archive/html/freetype-devel/2013-05/msg00000.html).

It's based on mupdf. It seems that mupdf is more suited to be embedded into / used for embedding other programs: latest mupdf (1.20, iirc) has a js console and I think you can interact with the viewer -- sort of the js console of the browser; I haven't seen how yet, perhaps you can add objects on the fly to the documents, in this case one can think of embedding a small luatex (no harms, after all mupdf it's already a big binary) and add (pdf)objects by scripting. -- luigi [-- Attachment #1.2: Type: text/html, Size: 1750 bytes --] [-- Attachment #2: Type: text/plain, Size: 496 bytes --] ___________________________________________________________________________________ If your question is of interest to others as well, please add an entry to the Wiki! maillist : ntg-context@ntg.nl / https://www.ntg.nl/mailman/listinfo/ntg-context webpage : https://www.pragma-ade.nl / http://context.aanhet.net archive : https://bitbucket.org/phg/context-mirror/commits/ wiki : https://contextgarden.net ___________________________________________________________________________________ ^ permalink raw reply [flat|nested] 13+ messages in thread

Hi Hraban, sorry if I’m misreading, but I’m afraid I wasn’t able to find any Paulo in the messages I have from this list. Now I wonder who he might be.
