Split, Combine and Compress PDF Files
Content-preserving transformations transformations of PDF files. Note qpdf does not read actual content from PDF files: to extract text and data you need the pdftools package.
pdf_split(input, output = NULL, password = "") pdf_length(input, password = "") pdf_subset(input, pages = 1, output = NULL, password = "") pdf_combine(input, output = NULL, password = "") pdf_compress(input, output = NULL, linearize = FALSE, password = "")
input |
path or url to the input pdf file |
output |
base path of the output file(s) |
password |
string with password to open pdf file |
pages |
a vector with page numbers so select. Negative numbers means removing those pages (same as R indexing) |
linearize |
enable pdf linearization (streamable pdf) |
Currently the package provides the following wrappers:
pdf_length: show the number of pages in a pdf
pdf_split: split a single pdf into separate files, one for each page
pdf_subset: create a new pdf with a subset of the input pages
pdf_combine: join several pdf files into one
pdf_compress: compress or linearize a pdf file
These functions to not modify the input file: they create new output file(s)
and return the path(s) to these newly created files.
# extract some pages
pdf_file <- file.path(tempdir(), "output.pdf")
pdf_subset('https://cran.r-project.org/doc/manuals/r-release/R-intro.pdf',
pages = 1:3, output = pdf_file)
pdf_length(pdf_file)
