SAOTk is an integrated set of Tk/Tcl Canvas Widgets for astronomical imaging and data visualization. The SAOTk widget set includes the following widgets:
Frame - FITS viewer for one image or one mosaic Panner - Thumbnail image of data and position control Magnifier - provides a 'magnifier' window into data Colorbar - controls color environment for application
In addition to ``classical'' support for imaging FITS data, manipulating colormaps, region marking, coordinate readout (including WCS), etc., SAOTk widgets also support arbitrary image rotation, advanced printing and graphics, image mosaics, and shared memory.
The SAOTk widgets will be incorporated into the next major release of SAOtng, a release that will allow the astronomical community to begin moving away from its primary dependence on Unix and X11. They also can be added to any standard Tk/Tcl environment to build custom data analysis and visualization applications.
