Description arspr 2014-10-23 14:15:01 UTC

Hi,

I'm no user of poppler but of Kovid's Calibre (http://calibre-ebook.com/) and this bug report arises by Kovid's suggestion about an issue in Calibre itself (https://bugs.launchpad.net/calibre/+bug/1375983)

The problem seems to be that certain new pdf files (http://usa.canon.com/CUSA/assets/app/pdf/brochures/EOS_7D_Mark_II_AF_guide_CUSA_9-2014.pdf?WT.mc_id=C126149) cannot be rendered by pdftoppm util which is used in Calibre.

As a wild guess it might be related to 256 bit AES encryption.

@Albert I would like to do "Implement SecurityHandler V6 in Poppler" project. The link to this project is given here https://community.kde.org/GSoC/2015/Ideas#Project:_Implement_SecurityHandler_V6_in_Poppler.

Great, work on it!

Comment 4 Sarvjeet Singh 2016-01-30 08:04:13 UTC

Cool.
Could please mentor me in this project? Also, How do I contact you?

If you're speaking about Google Summer of Code, that's not how it works, the application period is not even started.

If you're speaking about answering questions you may have. There's a poppler development mailing list.

I didn't mean GSOC. I am interested in this project and hope to finish it before GSOC application period starts. Actually I have taken this for my course project(B.Tech in IT). Also, I have some experience in open source contribution did for Mozilla and Julia so won't bother much.

OK, I'll use mailing list for this.

Will be fixed in next release.
