New in 0.12

  • switch from Gtk to Gtk4. Fixes REPL lag on Windows.
  • Julia 1.6 is now required

New in 0.11

  • switch from GtkReactive to GtkObservables. Reactive was essentially unmaintained, and Observables has a stronger technical foundation.
  • reductions in latency, particularly on Julia versions >= 1.8.

New in 0.5

ImageView has been rewritten from scratch. Effort was made to maintain backward compatibility where possible.

Breaking changes

  • The return value of imshow has changed; it is now a Dict that stores Gtk widgets, Reactive signals, etc.

Major features

  • This package now uses Gtk. Rendering is considerably faster in some cases, and the package is faster to load due to precompilation.

  • Navigation and zoom region are controlled by GtkReactive/Reactive signals, allowing one to more easily extract this information for reuse elsewhere. Examples are shown in the README.

  • A new contrast GUI is independent of any plotting package, leading to faster loading and faster time-to-first-plot.

  • One can now display objects that are not subtypes of AbstractArray. See test/cone.jl for a demonstration.

Deprecations

  • canvasgrid now returns more arguments; a deprecation warning encourages transitioning to the new syntax

  • pixelspacing is deprecated as a keyword (use an AxisArray instead)

  • The xy keyword has become axes, and it takes dimension integers or Symbols (if the image is an AxisArray)
