Overview

About

Maintained by Rory NolanCRAN page ↗GitHub ↗Website ↗Issues ↗

General purpose TIFF file I/O for R users. Currently the only such package with read and write support for TIFF files with floating point (real-numbered) pixels, and the only package that can correctly import TIFF files that were saved from 'ImageJ' and write TIFF files than can be correctly read by 'ImageJ' https://imagej.net/ij/. Also supports text image I/O.

Changes in 3.2.0

NEW FEATURES

write_tif() now uses a tags_to_write parameter that accepts a named list of TIFF tags, consolidating support for all writable tags (previously used individual parameters).
Support for writing imagedescription TIFF tag (tag 270) for OME-TIFF metadata.
Automatic metadata preservation: TIFF tags are automatically extracted from image attributes (e.g., from read_tif()) and included when writing, enabling round-trip editing without metadata loss.
Tag name normalization: tag names in tags_to_write are now case-insensitive and ignore hyphens/underscores.
Compression and bits-per-sample overrides: tags_to_write can now override compression and bits_per_sample parameters.

MINOR IMPROVEMENTS

Replace vapply() with purrr::map_chr() in tag normalization for cleaner, more consistent code style.
Refactored argument checking logic for better organization.

TESTS

Add comprehensive test suite for automatic metadata pass-through and attribute tag handling (39 new tests).
Add tests for compression override via tags_to_write (11 tests).

Install

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

install.packages("ijtiff", 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("ropensci/ijtiff")

Development version from ropensci/ijtiff. 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-ijtiff

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-ijtiff

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-ijtiff

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.
