pdf_gs() processes the pdf file with ghostscript. This may prevent issues with other pdf processing functions like pdftools::pdf_pagesize().

Usage

pdf_gs(input, output = NULL, ..., args = character(0L))

Arguments

input

Input pdf filename.

output

Output pdf filename. NULL defaults to tempfile(fileext = ".pdf").

...

Ignored.

args

Arguments to pass to ghostscript. We automatically add -dBATCH -dNOPAUSE -sDEVICE=pdfwrite -sAutoRotatePages=None -sOutputFile={output}.
