Find a bookmark by its title

Returns the 1-based bookmark_index of the first outline entry matching title, suitable for indexing back into pdf_doc_bookmarks()'s tibble. NA when no bookmark matches. Wraps FPDFBookmark_Find and walks the outline pre-order to map the PDFium handle back to the row index.

Usage

pdf_doc_bookmark_find(doc, title, password = NULL)

Arguments

doc

A pdfium_doc from pdf_doc_open(), or a character path.

title

Single non-empty character string.

password

Optional password for encrypted PDFs when doc is a path. Ignored when doc is already an open pdfium_doc.

Value

Integer scalar — the 1-based bookmark_index, or NA.

Details

PDFium's matching is case-sensitive and matches the full title string.
