PAWT (Picture Automation With Tcl) is a high-level Tcl interface for handling images with byte, short, int, float or double pixel values. The image data and meta information are stored in a Tcl dict.
PAWT needs the
fitsTcl extension for handling FITS files and the
img::raw extension for displaying
the image data in a Tk photo image.
