This is a plugin for Obsidian. It extracts Annotations from PDF Files.
This Plugin visits all PDF files in a given directory and extracts comments and highlights from the PDF files. It treats the first line of every comment as Topic for grouping the comments.
Assume we have in a folder in our Vault containing PDF files, e.g:
and we have highlighted the Julia Hello World Programm with a note 'Hello World':
In the editor (e.g. _Extract) we run the plugin's command Extract PDF Annotations (Hotkey Ctrl-P for all Commands). This will fetch all annotations in the PDF files in the current folder and sort them by Topic:
As such, you can relate comments for your topics (here 'Hello World') from several PDF files.
Extract PDF AnnotationsWorks when edititan a markdown note. Searches all PDF files in current Folder for annotations, and inserts them at the current position of the open note.Extract PDF Annotations on single fileWorks while displaying a PDF file. Extracts annotations from this file and writes them to the noteAnnotations for <filename>
- Use the first line of the comment as 'Topic' (and sort accordingly), or not
- Use folder name or PDF-Filename for sorting
[] single word highlights are not found. I need to dig deeper...
