You'll need to be a little more clear about what you're asking: 1) how to call a python program from VB -- I have no idea, try comp.lang.python, or a PyWin32 mailing list if there is one. Although calling a python program as a command line program from VB should be trivial -- but why use Python for that? Why not go all the way?
2) How to do this all in Python -- If you want a GUI, you need to choose a toolkit first -- I recommend wxPython, but TkInter, PYGTK, PyQT, etc are good options, too. 3) How to do the image generation/manipulation -- then PIL (and this list) may be the best place, but you could also just do it straight with the GUI toolkit (wxPython anyway). You might also want to use the "numpy" package -- it's a good way to manipulate arrays of numbers. 4) If you want the equivalent of video feedback, but without actual images, just numbers, then numpy is definitely a good way to go. If I wanted to write a program that demonstrated video feedback, I'd probably do the number crunching with numpy, and make a GUI to display and manipulate the results in wxPython. I'm not sure where VB would fit into this. -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [EMAIL PROTECTED] _______________________________________________ Image-SIG maillist - Image-SIG@python.org http://mail.python.org/mailman/listinfo/image-sig
