I tried Annotator, which shows the pdf content, but unsharp.
annotation-target: bb.pdf
Additional text …
I don’t see how to edit the file, once it is saved, so I edit it with Notepad++.
A transclusion ![[Uwe2]] does only show “Additional text …”, not the pdf.
As of today there is no way to show a (more than trivial) pdf file inside a markdown file with Obsidian - am I right?
