The goal of {ti} is to speed up common tasks for managing a TIFF collection, by providing 1) I/O using deflate compression by default (here we just wrap {ijtiff}), 2) conversion to other common 2D/3D image/array formats, 3) tools to go from a collection of 2D images to a single multi-frame TIFF and vice versa, and 4) simple common image processing tasks.
Install
You can install the latest version of {ti} with the following:
if (!require(pak)) install.packages("pak")
pak::pak("rogiersbart/ti")Use
All {ti} package functions have the ff_ prefix, so that reading a TIFF file is done through:
img <- ti::ff_read("input-file.tif")and writing can be done with:
img |> ti::ff_write("output-file.tif")All other functions operate on (an) input file(s), and directly write the results to (an) output file(s), like:
ti::ff_compress("input-file.tif", "input-file_compressed.tif")
ti::ff_tif2bob("input-file.tif", "brick-of-bytes.bob")
ti::ff_extract("input-file.tif", frame = 13, out = "frame.%frame.tif") Sensible output file path defaults are in place, which allows you to do:
ti::ff_compress("input-file.tif") # overwrite with a deflate compressed file
ti::ff_tif2bob("input-file.tif") # will change the extension to .bob
ti::ff_extract("input-file.tif", frame = 13) # will e.g. use extension .013.tif
