Is there any way to click on an image to magnify? in many books figures are too small. Ctrl + scroll does magnify the entire doc, but the img is pixelated.

Extremely good software. Always on my _bat-belt_. The author was one of the most active members of the old Business Of Software forums, IIRC. I always wondered how he could make money from a free PDF viewer.

Sounds like he doesn’t make money.

Yes. It seems so :-)

Is there any open source seamless PDF editor available given how pervasive is the PDF document nowadays? I really think that we need one and it has been long overdue.

What I meant by seamless is that all of the open source software that currently able to edit PDF document is dong it in a clunky way at best for example Krita and LibreOffice Draw. The resulting edited output document also is also looks distinct, in a bad way, from the original document unlike the output from Adobe PDF editor.

The big update of SumatraPDF was out yesterday [1]. There are a lot of bugs fix and improvement in the backlog [2]. [1] https://github.com/sumatrapdfreader/sumatrapdf/releases/tag/... [2] https://github.com/sumatrapdfreader/sumatrapdf/issues/3672

this is my "dark mode" via advanced options, e.g. warmer page and dark background:

  MainWindowBackground = #191919
  FixedPageUI [
   TextColor = #282828
   BackgroundColor = #ebdbb2
   SelectionColor = #2d938f
   ...
  ]
what I have been doing so far is switch between other modes with autohotkey by overwriting `SumatraPDF-settings.txt`. I'd share the little script but it suddenly broke a while back

Bless the heart of whoever looked at the PDF spec and said to themselves, "Nice, I'd like to writer a parser for this."

No joke. Yesterday I found out PDFs can have forms with JavaScript. https://tcpdf.org/examples/example_014/ How does this even work?

badly

Earlier quoted context omitted.

Dark mode and tab switching with the keyboard are 2 great additions to the best lightweight PDF reader EVER!!!

Tab switching with the keyboard was already possible previously, IIRC you can use Alt+ (or maybe Ctrl+ ) to switch to the N-th tab.

yes, CTRL+TAB and ALT+, I use them all the time.

Sumatra is great, though occasionally I wish it were possible to have something like Firefox's wrapped scrolling [1] where more than 2 pages can be shown side by side. On a reasonably large monitor, being able to quickly zoom out to see e.g. 30 pages (sometimes all the pages of a journal article) at the same time can be very useful. You can be on p. 20, then go and quickly look up a definition on p.2, then frictionle…

Love this view. I can't get pdf display on FF to invert colors. Is there a way? Then it would replace okular for me (which also does this overview mode)

Great retrospective of SumatraPDF from the author: https://blog.kowalczyk.info/article/2f72237a4230410a888acbfc... .

> The problem is that Gtk is ugly, Qt is extremely bloated and WxWidgets barely works.

Seems like the author didn't look at cross-platform toolkits since 90s.

If you are on linux and miss the snappiness of sumatra, try llpp. They use the same renderer. In fact, llpp has more features, like a better overview mode where you can get 3 pages on screen. Search does suck. llpp is written in Ocaml and a fantastic piece of software.

Wow, I just installed this for the first time and its performance blows both Adobe Reader (not an achievement) and Foxit (something of an achievement) out of the water! Nice work by these devs. And its install footprint is around 10% of those programs. What the hell is Adobe doing, I wonder, that makes their software so unbearably slow and painful to use?

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.

Acrobat Pro is pretty incredible. One of my favourite features is the following: on a scanned PDF after performing OCR you can edit the text and it will match the font. As in, it will create a new font based on the characters it found in OCR.

I’m a high school math teacher and scan dozens of textbooks every year. Adjusting a few words before printing to match what we did in class is a huge time saver for me.

Somehow my school division was able to buy me a one time fee perpetual license. I’m very happy with it.
