napari 0.5.4#

Monday, Sep 30, 2024

We’re happy to announce the release of napari 0.5.4!

napari is a fast, interactive, multi-dimensional image viewer for Python. It’s designed for exploring, annotating, and analyzing multi-dimensional images. It’s built on Qt (for the GUI), VisPy (for performant GPU-based rendering), and the scientific Python stack (NumPy, SciPy, and friends).

Highlights#

Another release with a lot of bug fixes, but also some (more!) improvements to Shapes layer performance (#7144, #7256), and a few nice usability/quality of life features!

  • you can now follow the value under the cursor around in images in 3D view as well as 2D (#7126)

  • Use standard keyboard shortcuts to zoom in and out (Command/Ctrl+=, Command/Ctrl+-) and to zoom-to-fit (Command/Ctrl+0) (#7200)

  • you can now save tiff files larger than 4GB (#7242)

Finally, we’re starting some work on tweaking the UI to make it more self-consistent, with the ultimate goal of adding functionality such as showing common controls when multiple layers are selected, so that, for example, you can select multiple layers and adjust all their opacity settings together. As the first step for this, the layer blending controls have been moved directly under the opacity control, so that all per-layer controls are next to each other in the UI (#7202)

Read on for all the changes in this version!
