split_pdf: Split and merge PDFs

Description

Split PDF into separate pages or merge multiple PDFs into one.

Usage

split_pdf(file, outdir = NULL, password = NULL, copy = FALSE)
merge_pdfs(file, outfile, copy = FALSE)

Value

For split_pdfs, a character vector specifying the output file names, which are patterned after the value of file. For merge_pdfs, the value of outfile.

Arguments

file: For merge_pdfs, a character vector specifying the path to one or more local PDF files. For split_pdf, a character string specifying the path or URL to a PDF file.
outdir: For split_pdf, an optional character string specifying a directory into which to split the resulting files. If NULL, the outdir is tempdir(). If file is a URL, both the original file and separate pages are stored in the R session's temporary directory.
password: Optionally, a character string containing a user password to access a secured PDF. Currently, encrypted PDFs cannot be merged with merge_pdfs.
copy: Specifies whether the original local file(s) should be copied to tempdir() before processing. FALSE by default. The argument is ignored if file is URL.
outfile: For merge_pdfs, a character string specifying the path to the PDF file to create from the merged documents.

# merge pdf
mf <- file.path(tempdir(), "merged.pdf")
merge_pdfs(sf, mf)
get_n_pages(mf)
