[Feature request] add/modify bookmark about pikepdf HOT 6 CLOSED

You already can manipulate the bookmarks data structure manually. Yes, I'd like to add this. Bookmarks have a lot of functionality associated.

Finally i got what I wanted by parsing and imitating existing cases.

outlines = pikepdf.Dictionary({
    "/Type": pikepdf.Name("/Outlines"),
    "/Count": 0
})
for i in enumerate(ordered_bookmarks):
    child = pikepdf.Dictionary({
        "/A": pikepdf.Dictionary({
            "/D": pikepdf.Array([
                pdf_writer.root["/Pages"]["/Kids"][i[0]],
                pikepdf.Name("/Fit")
            ]),
            "/S": pikepdf.Name("/GoTo")
        }),
        "/Title": pikepdf.String(i[1]),
    })
    if "/First" not in outlines:
        outlines["/First"] = child
    else:
        outlines["/Last"]["/Next"] = child
    outlines["/Last"] = child
    outlines["/Count"] += 1
pdf_writer.root["/Outlines"] = outlines

@OnlyFor , what is the variable ordered_bookmarks you are enumerating?

My quest is to find the page numbers that specifically a named bookmark refers to. I'm from the javascript world, so still trying to wrap my mind around python's style.

Do you have any examples that show a list of the bookmarks + their properties (namely just "Title" and "Page")?

Have a look at the PDF reference manual (ISO32000 2008) in section H.6 for a description of how the document outline works. In short it is a tree data structure and you have to decide how you want to traverse it. It's difficult to describe without diagrams. The reference manual is linked the pikepdf documentation.
