Comprehensive TIFF I/O with Full Support for 'ImageJ' TIFF Files
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.nih.gov/ij/>.
Also supports text image I/O.

Introduction
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.
ijtiffcan write TIFF files whose pixel values are real (floating-point) numbers;tiffcannot.ijtiffcan read and write text images;tiffcannot.tiffstruggles to interpret channel information and gives cryptic errors when reading TIFF files written by the ImageJ software;ijtiffworks smoothly with these images.
