Hello devs, I've whipped up quickly a couple of changes to the default PDF export of the XWiki platform, to try to make it look a little nicer. I created the issue here https://jira.xwiki.org/browse/XWIKI-15761 and the pull request here https://github.com/xwiki/xwiki-platform/pull/900 . I would like to merge that into master unless somebody has something against it, so please speak up now.
Longer story: I know that "nicer" is a subjective term, and that a lot more can be done to improve this default PDF export. My idea was that the current defaults we have (for the font family, for example, or the information we display in the pdf header/footer and the style associated) are not the result of an actual studied choice, iirc they are just defaults that were set like that in the first version of that export and never changed. Thus, I don't see why we couldn't slightly change these defaults (without changing the information displayed or risking regressions) to have a slightly better looking default PDF, while still allowing all customizations just they way they worked before. These modifications are not blocking nor replacing in any way the more serious improvements that can be done on the PDF export, they're just slightly improving the current defaults. Best regards, Anca
