Page dimensions in PDF points

Returns the width and height of page in PDF points (1 point = 1/72 inch). Accepts either a pdfium_page (preferred when you already have one) or a (doc, page) pair (convenience for one-shot inspection).

Usage

pdf_page_size(page, page_num = 1L)

Arguments

page

A pdfium_page from pdf_page_load(), or a pdfium_doc.

page_num

One-based page index. Only used when page is a pdfium_doc. Ignored otherwise.

Value

A named numeric vector with elements width and height.

Details

The returned dimensions are media-box dimensions in the page's default (un-rotated) orientation. If the page has a non-zero rotation (via the PDF /Rotate attribute or PDFium's runtime rotation), pdf_page_size() does not swap width and height. Query the rotation separately with pdf_page_rotation() if you need to know the on-screen orientation.

See also

pdf_page_rotation() for the rotation angle in degrees.

Examples

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