Package: texlive-latex-extra-doc Version: 2024.20250309-2
For an unadvertised reason, /usr/share/doc/texlive-doc/latex/webquiz/examples/*.png and /usr/share/doc/texlive-doc/latex/beautybook/inner_pics/titleimages/songeven.png have caNv chunks. This chunk is not standard and creates issues down certain tool chains; cf. http://bugs.debian.org/1115346. The documentations opened by `texdoc webquiz` and `texdoc beautybook` keep silent about this tag. If this tag is really necessary, document why; otherwise, remove it from the offending PNG files (`pngcrush -brute -ow -rem caNv file.png`).
