Read the raw bytes of an embedded file attachment

Returns the decompressed file contents of the attachment at attachment_index (1-based, as listed by pdf_attachments()). Wraps FPDFAttachment_GetFile.

Usage

pdf_attachment_data(doc, attachment_index = 1L)

Arguments

doc

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

attachment_index

One-based index of the attachment in the document's attachment table.

Value

A raw vector of file bytes.

Details

Use the returned raw vector directly with writeBin() to save the embedded file to disk without re-encoding, or pass it to a downstream parser (e.g. xml2::read_xml(rawToChar(bytes)) for XML attachments).
