Tcl and Tk Interface to ImageMagick TclMagick is a Tcl extension that works with the ImageMagick image manipulation libraries. TkMagick is a small, simple extension that lets you pass images back and forth between Tk and the TclMagick extension. Requirements TclMagick runs with pure Tcl, no Tk is required. It needs an installed ImageMagick library. The Windows version also requires Ghostscript for standard postscript fonts. TkMagick needs Tk, of course.
