How to remove bookmarks/outlines?

[mitchpaulus]

I'm looking to remove existing bookmarks/outlines from a PDF when merging. There is the add_outline_item but I did not see any methods corresponding to removal. A simple web search didn't turn up anything useful.

Is there a canonical way to do this within PyPDF2?

the append/merge functions has a parameters to not copy the outlines. to remove a single outline, there is currently no function to easily remove it. Will prepare something

Hi, is there any workaround for that as of yet?

As far as I understand the linked issue, this should work (although I have not tested it):

from pypdf import PdfWriter

writer = PdfWriter(clone_from='file.pdf')
for outline in writer.outline:
    outline.remove_from_tree()
writer.write('out.pdf')

If it works for you, consider opening a PR to document this.
