Compress a PDF using ghostscript

When pdfout is missing it defaults to <input>_gso.pdf

gscompress(pdfin, pdfout, firstpage, lastpage, pdflevel = "1.5",
  gsopts = "", Force = TRUE)

Arguments

pdfin, pdfout	Input and Output PDFs
firstpage, lastpage	Page range (defaults to firstpage = 1, lastpage = last in PDF)
pdflevel	Minimum compatible PDF version of output file
gsopts	Further options for ghostscript
Force	When FALSE, only update file for newer input

Value

character vector with path to pdfout

Details

This seems to work well for pdflatex output

Examples

if (FALSE) {
gscompress('statistics.pdf',gsopts='-dSubsetFonts=true -dEmbedAllFonts=true')
}
