Pdf so badly needs a standard open source reference implementation. the problem with java is that it isn’t easy to reuse in other programming environment...

something in C, or anything that compiles through LLVM would probably be a better choice i think.

I tried to find a good comparison to PDFBox but came up short!

I'm one of the maintainers of OpenPDF. Please give it a try and post your feedback. Also, if you are using iText 1.2.x, it's time to update to OpenPDF, which should be compatible.

Google's PDFium which is used in Android and ChromeOS is fast becoming the reference implementation to target: https://opensource.google.com/projects/pdfium

What's wrong with pdfium?

Is there a standalone client based on pdfium ?

It uses custom google build systems that are difficult to use independent of a chromium build. Last time I tried I was unable to get it to build.

It's not packaged as far as I can tell separately from chromium and chromium doesn't ship it as a reusable library. Not sure if it has a stable interface, probably not.

It doesn't have any frontend other than chromium.

That is actually what I thought this OpenPDF thing was.

I feel that the name is very unfortunately chosen - it's too generic, should have had a "J" in it at least to denote that it is a Java library. JOpenPDF, perhaps.

There's already plenty of open source implementations of PDF parsing: Ghostscript, MuPDF, XPDF, Poppler, Pdfium, just to name the first few that come to mind.
