tiffit

Lightweight command-line interface for handling tiff files in BigTIFF format.

Convert, extract information, and concatenate. That's it. Nothing fancy.

installation and usage

Install with pip and then use from command line.

pip install tiffit

# convert file into a well-behaved bigtiff file
tiffit convert old.tiff new.tiff

# get info about file without loading into memory
tiffit info filename.tiff

# concatenate two tiff files into a single bigtiff file
tiffit concat file1.tiff file2.tiff newfile.tiff

Notes / caveats

• If there is other information you would like read out from the info command, please let me know, bearing in mind I am trying to keep this interface fairly universal and simple.
• For an excellent overview of tiff (thousands of incompatible file formats), see [https://www.fileformat.info/format/tiff/egff.htm](this excellent overview). It is a bit dated, but is still the best thing I've found.
• If you need a package with more complexity, see:
  • opencv
  • pillow
  • tiffile
  • tifftools

To do

• add keyword argument to info so user can check on specific image in stack. Better yet, don't allow mixing of formats just make this a pure bigtiff library: add autoconversion of concatenated files.
• add verbosity controller for convert and concat.
