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.
