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

(I wrote SumatraPDF). In fairness, I didn't write the PDF rendering. That is indeed quite a tall order. I used to use poppler and switched to mupdf (was more active at the time, poppler seems to have picked up pace since). The core PDF feature set isn't that bad to implement. From what I've seen, the bad / complex parts are: - stuff they added years later, like some XML stuff (of course you had to add XML in 2000!),…

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…

SumatraPDF is among the OSS PDF tools I use. Since Adobe is pushing a more aggressive stance for monetization of Acrobat, I am trying to replace selected PDF workflows with OSS. Here are some of the tools I use. qpdf removing passwords, unlocking PDFs, conversion install in WSL with apt-get install qpdf remove password with qpdf --decrypt --password="" input.pdf output.pdf PDF4QT - Open Source PDF Editing Deleting, S…

Like others have mentioned, Sumatra is one of a few Windows-only utilities that I routinely miss when on Mac or Linux, primarily due to two simple interactions which I miss every day viewing schematics, mechanical/technical drawings or datasheets -- Alt + Scroll == Zoom and Right Click + Drag == Pan. Does anyone know of any viewers on Mac or Linux that provide these two features? Skim on Mac implements Option + Scrol…

FoxIt does zoom on Ctrl+Scroll, and Pan on Left Click+Drag. Runs on Mac and I'd assume linux. Close enough? I assume if you REALLY want to go nuclear on it, there is some shareware app that will let you do per-app keyboard emulation and rebind inputs "in flight" or something. I believe https://www.keyboardmaestro.com/main/ is the standard solution.
