Title: | Split, Combine and Compress PDF Files |
---|---|
Description: | Content-preserving transformations transformations of PDF files such as split, combine, and compress. This package interfaces directly to the 'qpdf' C++ API and does not require any command line utilities. Note that 'qpdf' does not read actual content from PDF files: to extract text and data you need the 'pdftools' package. |

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 to rotate |
linearize |
enable pdf linearization (streamable pdf) |
stamp |
pdf file of which the first page is overlayed into each page of input |
angle |
rotation angle in degrees (positive = clockwise) |
relative |
if |
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
pdf_rotate_pages: rotate selected pages
These functions do not modify the input
file: they create new output file(s)
and return the path(s) to these newly created files.
