napari 0.4.18

We're happy to announce the release of napari 0.4.18!
napari is a fast, interactive, multi-dimensional image viewer for Python.
It's designed for browsing, annotating, and analyzing large multi-dimensional
images. It's built on top of Qt (for the GUI), vispy (for performant GPU-based
rendering), and the scientific Python stack (numpy, scipy).

This is primarily a bug-fix release, addressing many issues from 0.4.17 (see
"Bug Fixes", below). However, it also contains some performance improvements and
several exciting new features (see "Highlights"), so read on below!

For more information, examples, and documentation, please visit our website:

Highlights

  • Drawing polygons in the Shapes layer can now be done much faster with
    the new lasso tool (napari/napari/#5555)
  • Surface layers now support textures and vertex colors, allowing a whole new
    type of dataset to be visualised in napari. Have a look at
    surface_multi_texture.py and surface_texture_and_colors.py in the
    examples directory for some pretty demos! (napari/napari/#5642)
  • Previously, navigating an image required switching out of whatever drawing
    mode you might have been using and going back to pan/zoom mode. Now you can use
    the mouse wheel to zoom in and out in any mode. (napari/napari/#5701)
  • Painting labels is now much, much faster (achieving 60fps even on an 8k x 8k
    image) (napari/napari/#5723 and
    napari/napari/#5732)
  • Vectors layers can now be displayed with two different styles of arrowheads,
    instead of just plain lines. This removes a longstanding limitation of the
    vectors layer! (napari/napari/#5740)
