Using Tcl extensions with Python?
How do you setup a Tcl extension to be accessible through Python? I understand that I'll have to use native Tcl calls to use it (tk.call() etc), but I can't figure out where to put the files or how to initialize them so I can call them. The package I would like to use is TkPNG: http://www.muonics.com/FreeStuff/TkPNG/ Thanks. -- http://mail.python.org/mailman/listinfo/python-list

To check what directories are part of auto_path, start tclsh and enter "set auto_path". Follows a sample code to demonstrate how to load the required package: import Tkinter root = Tkinter.Tk() tkpnglib = "/usr/lib/tkpng0.9" root.tk.eval(""" global auto_path lappend auto_path {%s}""" % tkpnglib) root.tk.eval("package require tkpng") If tkpng were installed in some directory belonging to auto_path, then you wouldn't need that call to tk.eval. And.. for tkpng specifically, you won't need tk.call to use it, you just need to create your images using Tkinter.PhotoImage with a "png" type. > Thanks. > -- > http://mail.python.org/mailman/listinfo/python-list > -- -- Guilherme H.

ARGH, Tcl!!! ;-) I know that's not the question, but do you know PIL (http://www.pythonware.com/products/pil)? -- http://mail.python.org/mailman/listinfo/python-list

Yes, I know about PIL. However, I need use PNGs with a full alpha channel. PIL only seems support simple transparency, whereas TkPNG seems to work as expected with them. If I am incorrect in this, then please let me know how to use it! Thanks. -- http://mail.python.org/mailman/listinfo/python-list
