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.

Currently parsers for FITS, FLIR, PPM and RAW image formats are available.

PAWT needs the fitsTcl extension for handling FITS files and the img::raw extension for displaying the image data in a Tk photo image.
