Load a single page from an open PDF document

Returns a pdfium_page handle bound to its parent doc. The page is garbage-collected with a finalizer that calls FPDF_ClosePage; call pdf_page_close() explicitly when you need deterministic release. The page keeps the parent document alive for as long as the page is reachable, so it is safe to drop your reference to doc while still holding a page.

Usage

pdf_page_load(doc, page_num = 1L)

Arguments

doc

A pdfium_doc from pdf_doc_open().

page_num

One-based page index. Must satisfy 1 <= page_num <= pdf_page_count(doc).

Value

A pdfium_page object.

Examples

fixture <- system.file("extdata", "fixtures", "minimal.pdf",
  package = "pdfium"
)
if (nzchar(fixture)) {
  doc <- pdf_doc_open(fixture)
  page <- pdf_page_load(doc, 1)
  pdf_page_close(page)
  pdf_doc_close(doc)
}
