Overview

About

Maintained by Trevor L. DavisCRAN page ↗GitHub ↗Website ↗Issues ↗

Edit 'XMP' metadata https://en.wikipedia.org/wiki/Extensible_Metadata_Platform in a variety of media file formats as well as edit bookmarks (aka outline aka table of contents) and documentation info entries in 'pdf' files. Can detect and use a variety of command-line tools to perform these operations such as 'exiftool' https://exiftool.sourceforge.net/, 'ghostscript' https://www.ghostscript.com/, and/or 'pdftk' https://gitlab.com/pdftk-java/pdftk.

Changes in 0.3.1

New features

------------

New get_bookmarks_augmented() which augments get_bookmarks_pdftk()'s support for bookmark page numbers with get_bookmarks_pdftools()'s new support for whether bookmarks should start open or closed (#62).
docinfo() objects now support arbitrary (non-standard) info dictionary entries (#7). Read/write support among the various backends is as follows:
get_docinfo_pdftk()/set_docinfo_pdftk() support reading and writing them.
get_docinfo_exiftool()/set_docinfo_exiftool() support reading and writing them.
get_docinfo_pdftools() supports reading them.
set_docinfo_gs() supports writing them.

Bug fixes and minor improvements

Show all changes in 0.3.1Hide the rest of the changes in 0.3.1

--------------------------------

Fixes set_bookmarks() bug where tempfile wasn't being deleted if input == output (@djvill, #63).
get_bookmarks_pdftools() now reports positive/negative count (as well as open) using pdftools::pdf_toc()'s new is_open list element (#62). This requires pdftools (>= 3.8.0).
get_bookmarks() now prefers the new get_bookmarks_augmented() when supported.
Calls to the pdftk command-line tool to read bookmark/documentation info metadata now time out after 60s by default (configurable via the xmpdf_pdftk_timeout option) rather than being able to hang indefinitely on a pathological pdf outline.

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

install.packages("xmpdf", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("trevorld/r-xmpdf")

Development version from trevorld/r-xmpdf. Installs pak first if it is not already available.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-xmpdf

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

bspm (used by r2u) also needs make: sudo apt install make

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-xmpdf

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-xmpdf

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
