Add lines to a pdf

pdf_add_lines() adds lines along the components of a print-and-play layout.

Usage

pdf_add_lines(input, output = NULL, ..., layout = "poker_3x3", gp = gpar())

input: Input pdf filename.
output: Output pdf filename. NULL defaults to a tempfile() with a ___pnpmisc.pdf file extension.
...: Passed to pdf_add_overlay().
layout: Either a layout preset name in layout_names() or a data frame with layout data (as returned by layout_grid()). A preset name is centered on the paper size of the input pdf's (selected) pages as inferred by pdf_paper(); it is an error if those pages don't all share a supported paper size.
gp: Passed to grid::grid.segments().

output pdf file name invisibly. As a side effect creates pdf file with added line segments.
