Ginga is a toolkit for building viewers for scientific data in Python, particularly astronomical data. It also includes a reference viewer for viewing FITS (Flexible Image Transport System) files.
The Ginga viewer is based on an image display widget that supports:
- Zooming and panning
- Color and intensity mapping
- A choice of several automatic cut levels algorithms, and
- Canvases for plotting scalable geometric forms.
In addition to the image display widget, the Ginga viewer provides a flexible plugin framework for extending the viewer with many different features.
A relatively complete set of standard plugins is provided for features that we expect from a modern viewer: panning and zooming windows, star catalog access, cuts, star pick/fwhm, and thumbnails.
