Dear all,
I implemented PDF rendering in Qt application.
My opinion is that Poppler is not the best piece of open source code,
look the code in comparison to MuPDF, it is C but clean C and run on
embedded devices.
Rather Poppler is more like a pile-up of crappy codes. Some years ago,

I think the point of bundling qtpdf into the qtwebengine repository is that
they will be built together, from the same sources. I hope it also means that

ALL of them? How quickly?
Please make sure that either you're releasing within two weeks of *every* CVE
or that I can use

I don't see what value a Poppler-based Qt PDF rewrite would bring us
considering that there is already a poppler-qt that can be used directly,

And? If Poppler is a superior alternative, then people can accept its GPL
requirements or not display PDF.

Hi,
I suggest to promote Qt PDF to a Qt module. For Qt 5.14, it will be in Tech
Preview state, and Shawn Rutledge is volunteering to be the maintainer.
Although still staying an independent library from the user's perspective, it
will be hosted and built in the qtwebengine.git repository.
