lj·rk @ #EH22Again looking at <a href="https://todon.eu/tags/PDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PDF</a> things at work (malicious PDFs, content/mime-type detection). And again and again I just *love* <a href="https://todon.eu/tags/QPDF" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QPDF</a> <a href="https://qpdf.readthedocs.io/en/stable/" rel="nofollow noopener noreferrer" target="_blank">https://qpdf.readthedocs.io/en/stable/</a>Basically, QPDF is a tool to "convert" any PDF into... PDF. Many PDFs are often binary files (due to compression and embedding of binaries), this is a hassle to edit/manipulate (my use case). But it's possible to make any PDF a "plain text file" that's also a valid PDF. QPDF does just that. You can then edit tags, extract info, delete watermarks *cough*, etc., with your text editor. The resulting PDF ain't correct anymore, likely (offsets and jumps addresses being wrong) but you can ask QPDF to recalculate them – et voila!

Adonay Felipe Nogueira<a href="https://mastodon.social/@kirschner" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@kirschner</a> To make myself clear, I don't know if the second part is possible (taking raw data to create <a href="https://ecodigital.social/tags/pdf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PDF</a> with <a href="https://ecodigital.social/tags/qpdf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QPDF</a>).<a href="https://fosstodon.org/@libreoffice" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@libreoffice</a>

I see this using <a href="https://ecodigital.social/tags/qpdf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QPDF</a>'s “---raw-stream-data” option.One thing that might be able to do is try using that same command for <a href="https://ecodigital.social/tags/qpdf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#QPDF</a>, spotting where to change stuff (in case there is a specific spot for the change) and seeing how to make a new <a href="https://ecodigital.social/tags/pdf" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#PDF</a> from that raw data.
