Construct a pdfium_annot handle for one annotation

Looks up the annotation at annotation_index on page and returns a handle. Wraps FPDFPage_GetAnnot.

Usage

pdf_annot_at(page, annotation_index, page_num = 1L)

Arguments

page

A pdfium_page or pdfium_doc.

annotation_index

One-based annotation index on the page.

page_num

One-based page index (only used when page is a pdfium_doc).

Value

A pdfium_annot handle.

Details

Most callers don't need this directly — pdf_annotations() returns the full list of handles. pdf_annot_at() is the targeted lookup, useful when you have an index from a tibble row.
