Images not displayed - output data image/png - R notebook

[eliselavy]

Problem of images displayed related to R's notebook :

• with notebook tagged with aspect-ratio / w-Xpx / h-Xpx

https://github.com/jdh-observer/jdh001-9HcfToh7EYm8/blob/main/skim-article.ipynb https://journalofdigitalhistory.org/en/notebook-viewer/JTJGcHJveHktZ2l0aHVidXNlcmNvbnRlbnQlMkZqZGgtb2JzZXJ2ZXIlMkZqZGgwMDEtOUhjZlRvaDdFWW04JTJGbWFpbiUyRnNraW0tYXJ0aWNsZS5pcHluYg==

=> the table of content is ok - but no figures displayed

• with notebook not tagged https://github.com/jdh-observer/jdh001-9HcfToh7EYm8/blob/main/1_load_train_7075.ipynb

The encoding was not right for the background-image css property, I've removed newlines in base64 encoding and it works. in principle this could be set from python code itself it seems, see https://stackoverflow.com/questions/30647219/remove-the-new-line-n-from-base64-encoded-strings-in-python3, they add newline=false No idea why R outputs newlines, but it will be fixed as soon as PR https://github.com/C2DH/journal-of-digital-history/pull/510 is merged.
