An astronomical image viewer and toolkit
Ginga is a toolkit designed for building viewers for scientific image data in Python, visualizing 2D pixel data in numpy arrays. The Ginga toolkit centers around an image display class which 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 this widget, a general purpose ''reference'' FITS viewer is provided, based on a plugin framework. Ginga is distributed under an open-source BSD licence.
