A pure OCaml library for reading TIFF files. The underlying IO mechanisms are expected to be provided by the user using a library of their choice. For example, you could use Eio.
ocaml-tiff is not yet released, until it has been you will need to pin it to use it.
opam pin -yn git+https://github.com/geocaml/ocaml-tiff
opam install tiff
To run the test suite, you can run dune runtest. To run the benchmarks use dune build @runbench -f (the -f will run the benchmarks unconditionally of whether the required dependencies have changed).
