Ahh gotcha. This should still be straight forward. Just don’t know of a generic format to export overlays/cordinates. Everyone has a opinion on how this should be done and measured and there are different standards for pdf libraries and print etc. not complicated though.

That was my feeling as well - it’s not necessarily complicated, it’s just so niche as to not have anyone making it. Today I found this GitHub repo which I may try tinkering with on the weekend: https://github.com/highkite/pdfAnnotate

yeah, main things are tracking overlay collision, groups like radio buttons, where you start your measurements from top left or bottom, dpi, and zoom levels. built systems for it using itext and websupergoo abcpdf. (backend for manipulating pdfs, tamper sealing etc.) and front end uses a image of the rendered pdf page that was extracted. This is a bit different from pdfjs but also scales well. PS pdf standards suck. :(

Or Linux Red Hat, iText Lib ( open sourced but under AGPL) etc. There is tons of open-source out there under commercial terms.

Yeah but this isn't open source. It's proprietary with source available, despite what you claim in numerous places throughout this thread. You're building a proprietary product on top of an open source project. You also chose a name that creates the impression that you built the original open source project, which you don't appear to be contributing anything back to. Comparing yourselves to Red Hat has to be a joke,…

No, Express will be available under dual AGPL/commercial license.

Am I missing something? Why should I pay 5000 for a pdf viewer, with features dozens of other pdf viewers have?

The talk is not about pdf viewers but about framework/APIs that developers can use to build all those 'others' solutions. pdfjs.express makes this a piece of cake, you get the source, and companies can outdo competition will less developer $$$ sunk into reinventing the wheel

I spent about three years building the support for PDF into my graphics editor https://www.Photopea.com . While other editors "add stuff on top of PDF", Photopea "chews through" each byte of a PDF, and tries to make as much sense of it as possible. You can rewrite the existing text (with the same formatting), edit bézier curves, edit gradient fills. You can edit bitmaps on a pixel level. You can see the parameters as…

sorry for my dumb question, but i was looking to add a simple arrow. Can't find it. Where is it hiding? :) Thx

You can find a picture of an arrow online and copy-paste it into your document :) or you can draw your arrow with a Brush tool, or with a Pen tool, etc :)

Dude, this is incredibly awesome! I've never heard of it even though this is something I've been looking for for a long time. I bet your software can get extremely popular if you can market it better.

I've immediately posted it on HN (hopefully I won't be downvoted just for linking my own post).

This is actually great! For many (but not all) files works much better than pdf editing in Inkscape which I was using up to today.

Two suggestions: 1. Make it clear to users why install button is greyed out. I know it, but most won't. 2. Allow login with any oauth provider, not everyone likes to be tracked across the web
