Work in progress See screenshots and videos below for the current state. I'm hoping this will be mostly working in early 2025.
This is a reworking of nip2 for the gtk4 UI toolkit and the vips8 image processing library.
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. This makes it convenient for developing image processing systems since you can watch pixels change as you adjust your equations.
Because nip4 uses libvips as the image processing engine, it can handle very large images 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.
It has a batch mode, so you can run any image processing system you develop from the command-line and without a GUI.

There's a zip for each version on the releases
page. Download
vips-dev-w64-all-8.16.0-nip4.zip, unzip somewhere, and run bin/nip4.exe.
We hope to have a homebrew formula soon.
There's a PR to add nip4 to flathub here:
Once we get a stable release, nip4 will be added to flathub. You can install one of the test releases from that PR with eg.:
flatpak install --user \
https://dl.flathub.org/build-repo/165060/org.libvips.nip4.flatpakref
Download the sources, then build and install with eg.:
cd nip4-x.y.x
meson setup build --prefix /my/install/prefix
cd build
meson compile
meson test
meson install
Check the output of meson setup carefully.
Clone:
https://github.com/libvips/build-win64-mxe
Then see this PR:
Checkout that branch and build with eg.:
./build.sh --with-nip4 all
Add the flathub repo, if you don't already have it:
flatpak remote-add --if-not-exists \
flathub https://flathub.org/repo/flathub.flatpakrepoInstall the gtk4 SDK and runtime:
flatpak install org.gnome.Sdk//47
flatpak install org.gnome.Platform//47Allow file. Recent security changes to git will cause submodule checkout
to fail inside flatpak. If you get errors like fatal: transport 'file' not allowed, re-enable file transport with:
git config --global protocol.file.allow alwaysYou need the latest flatpak-builder (the one in deb is not new enough),
install with:
flatpak install org.flatpak.Builder
Build and try running it:
flatpak run org.flatpak.Builder --force-clean --user --install build-dir org.libvips.nip4.json
flatpak run org.libvips.nip4 ~/pics/k2.jpgForce a complete redownload and rebuild (should only rarely be necessary) with:
rm -rf .flatpak-builderCheck the files that are in the flatpak you built with:
ls build-dir/filesUninstall with:
flatpak uninstall nip4-
niftiio is annoying to build, skip it.

x265 is annoying to build, skip it

we skip imagemagick as well, too huge
Install the appdata checker:
flatpak install flathub org.freedesktop.appstream-glib

On success, merge to master.
