I favor to learn books in PDF format (and never in ePUB). For this, I exploit Preview, and naturally I exploit bookmarks (menu bar > Instruments > Add Bookmark, or Command-D). The issue is that some books would not enable so as to add bookmarks to their starting or finish.
For instance, the e-book I am studying at the moment is "Easy methods to Learn a E-book" by Mortimer Adler and Charles Van Doren, 1972 version, digitized by the Web Archive in 2022 with funding from Kahle/Austin Basis: https://archive.org/particulars/howtoreadbook0000adle_y9v4. (May be downloaded, for testing functions, right here: https://file.io/oHGlSLYQdaHd.)
If I add a bookmark to a "common" web page, e.g., web page 100, the bookmark is added efficiently:
But when I attempt to add a bookmark to a "not so common" web page, e.g., web page V, with the desk of contents, the bookmark is added to the quilt as an alternative:
Is it doable to stop this from occurring? What I’ve already tried is "Menu bar" > "File" > "Export" > "Format": "PDF" > "Create PDF/A" and/or "Embed Textual content".
[x] Create PDF/A
[ ] Create Linerized PDF
[ ] Embed Textual content
[x] Create PDF/A
[ ] Create Linerized PDF
[x] Embed Textual content
[ ] Create PDF/A
[ ] Create Linerized PDF
[x] Embed Textual content
If utilizing "Embed Textual content" solely, all the pieces is similar. If utilizing "Create PDF/A", the bookmarks are added efficiently however are displayed within the aspect bar as intervals (…… …. ….).
I do not need to use a unique PDF viewer (Preview is ok for me), however I am OK with the concept to make use of some utility to regulate PDF as a center step. However which one and the way?
