  window and a table or plot viewer is running in the channel

Ginga v5.1.0

• Fixed an issue where --modules option did not start a global plugin automatically

• Fix for delete_row() in GridBox widgets
• Fix for TextEntry widget in pg backend

Ginga v4.1.0

• change implementation of splash banner to a pop-up modal dialog with version string
• fixed menubar integration on Mac OS X
• fixed an issue with auto cuts saved parameters not being loaded correctly
• fixed an issue with certain auto cuts methods not getting enough samples when the image size is very small
• removed old, deprecated StandardPixelRenderer
• RGB mapping has been refactored to use a pipeline
• Removed deprecated preload feature
• Fix for focusing plugins that have no GUI
• Added feature to reset viewer attributes between images (can be used synergistically with the "remember" feature). See Reset (Viewer)" and "Remember (Image)" settings in the "Preferences" plugin.
• Fixed bug with pg backend loading icons
• Pick plugin settings now has options to set the autozoom and autocuts settings for the "Image" and "Contour" viewers (see "plugin_Pick.cfg" file in .../ginga/examples/configs)

Ginga v4.0.1

• fixed a DeprecationWarning with jupyterw back end
• fixed a bug for Toolbar plugin that prevented N-E and N-W orientation from working as well as contrast restore
• fixes a bug in exporting ginga canvas objects to astropy regions objects and the test suite for it

Ginga v4.0.0

• fixed getattr functionality in Bunch

• removed the "mock" backend; use "pil" backend for similar purposes

• fixed a longstanding issue where events registered on a canvas could be masked by default key/cursor bindings (not associated with a mode). This meant, for example, that only certain keystrokes could be captured by an event handler registered on a ginga canvas, because any keystrokes that had a default binding would take precedence. Now such bindings are only executed if the event is not handled by any active canvas bindings.

• Removed the "Quick Mode" and "From Peak" options in the Pick plugin to simplify operation.

• Many deprecated camelcase (non-PEP8) methods were removed. Use the "snake-case" names instead.

• Fixed an issue with setting the scale manually in the Preferences plugin

• Fixed a bug that can cause an incorrect cropping of image when the window is resized

• Refactor modes from Bindings module into separate modules:

  • modes can now be written and understood as having a very similar structure to a plugin.
  • mode docstrings can be written and maintained better to document the modes and the code implementing a mode is much easier to understand since it is encapsulated rather than all mixed together in one huge file.

• Added an AutoLoad plugin that can monitor a folder for new files and load them.

• Fixed a bug in the Overlays plugin where the overlay value was reported as the value under the cursor rather than the data value

• Fixed an issue with loading RGB images with opencv-python

• Fixed an issue where manual cut levels changes weren't reflected in the Thumbs icon

• ScreenShot now correctly captures the background color of the viewer

• Fixed a DeprecationWarning related to use of entry points

• ColorMapPicker plugin can now be launched as a local or global plugin
