      nip4 is a spreadsheet-like interface to the libvips image processing
      library. You create a set of formula connecting your objects together,
      and on a change nip4 will recalculate.  Because nip4 uses libvips
      as the image processing engine it can handle very large images,
      recalculates quickly, and only needs a little memory.  It scales to
      fairly complex workflows: I've used it to develop systems with more
      than 10,000 cells, analyzing images of many tens of gigabytes.

    </p>
    <p>

      nip4 can load all workspaces from nip2, the previous version of this
      program.  It has a batch mode, so you can run any image processing
      system you develop from the command-line and without a GUI.

    <release version="9.0.16" date="2026-02-01">
      <description>
        <p>

          This build adds more improvements to nip4's programming language,
          including pattern matching for lambdas and better scoping for list
          comprehensions. Startup is faster thanks to deferred compilation,
          and the flatpak binary bundles an ImageMagick binary for wider file
          format support.
