PDF output separation preview
Dear #GIMP #INKSCAPE #SCRIBUS #TEX #LATEX and #PDF #opensource and #freesoftware lovers...
Do you know any #foss / #floss application that can preview output separation on a PDF file like Adobe Acrobat pro does?
I have been tried hard, even using javascript with #pdfjs but I couldn't find something very suitable for doing #prepress with opensource.
I am also ok with any #web applications.
Thanks... 🙏

@juergen_hubert try #PDFjs in #Firefox...
:librewolf: #LibreWolf's obsession with preventing everything HTML canvas is gettin on my nerves... It even ruins pasting images into the built-in #PDFjs PDF viewer, but you only realize that AFTER you're done and open it in another viewer, to realize that the image is all f*cked up. 🙄
Pour cette deuxième journée du hackathon de @FIPHFP et #DINUM, le projet #PDFJS de @mozillaofficial @firefox est un des sujets permettant de contribuer

Thomas Rinsma decided to abuse PDF field objects to render monochrome grid, and combine it with keystroke-entry in a text field to receive inputs – that’s how #PDFTris, a playable Tetris in a PDF file was born.
It's ridiculous how good #PDFjs is as a PDF viewer and even editor. I do like #Evince et al., but man is PDF.js better in many cases (for me):
- Umlauts/special characters in forms just work
- PDF opens instantly from this Samba server, in Evince takes ages to load
- can paste images into PDF (e.g. for 'signing' 🙃)
- can place free text
- etc.
Feels like there should be a standalone PDF.js desktop app, but that'll just be a weird Electron app then I guess...

PDF.js has isEvalSupported enabled by default.🤦

Kind of impressed at the quick bugfix turnaround I sometimes get when reporting issues in specific components of #Firefox ; this week, within the span of a few days, my report at https://bugzilla.mozilla.org/show_bug.cgi?id=1875547 led to this algorithmic #performance optimization in #PDFjs: https://github.com/mozilla/pdf.js/pull/17574
It's not yet multithreaded like what I was requesting in the bug report to begin with, but hey, any performance improvement is good to have.
I should have filed this #usability enhancement request in #PDFjs (used by #Firefox, #Chromium, #GNOMEWeb / #WebKitGTK, #NextCloud, etc.) years ago: the Print and Save buttons should show some labels in the toolbar when there is enough horizontal space to do so. It's a terribly confusing #UX for non-geeks to not make those prime actions obvious and explicit in a #PDF reader that sits between #browsers and the desktop. https://github.com/mozilla/pdf.js/issues/17569
Are you as annoyed by the #pdfjs #Javascript PDF renderer built into #webkit as I am? Well: as of now it seems you cannot really turn it off except by compiling it out. So, here is how to do it on #Debian #bookworm:

Uh, apparently #KDE #Okular can't display alt text on images. Does it completely ignore it, or is it only read by screen readers?
For example, the following LaTeX code generates a PDF that contains an image with alt text:
```
\usepackage{pdfcomment}
\pdftooltip{\includegraphics{img.png}}{This is the ALT text}%
```

set "pdfjs.viewerCssTheme" to 2 to force #darkmode
