In ropensci/ijtiff: Comprehensive TIFF I/O with Full Support for 'ImageJ' TIFF Files

ijtiff

This is a general purpose TIFF I/O utility for R. The tiff package already exists for this purpose but ijtiff adds some functionality and overcomes some bugs therein.

• ijtiff can write TIFF files whose pixel values are real (floating-point) numbers; tiff cannot.
• ijtiff can read and write text images; tiff cannot.
• tiff struggles to interpret channel information and gives cryptic errors when reading TIFF files written by the ImageJ software; ijtiff works smoothly with these images.

The github repo of ijtiff is at https://github.com/ropensci/ijtiff.

Installation

You can install the released version of ijtiff from CRAN with:

install.packages("ijtiff")

You can install the released version of ijtiff from GitHub with:

How to use ijtiff
