Gimp provides more tools to achieve different Image processing effects. It is script-able in Python. U may want to consider Gimp + Python: http://www.jamesh.id.au/software/pygimp/
Image.show() just calls the picture viewer in the OS. If Ur using windows, U may want to call a function to perform "Open with" U can also achieve similar functionality using Pygame: http://pygame.org/ On Mon, Mar 2, 2009 at 2:51 PM, Anand Balachandran Pillai < abpil...@gmail.com> wrote: > On Sun, Mar 1, 2009 at 1:25 PM, Arunabha Adhikari > <arunabha.adhik...@gmail.com> wrote: > > Dear friends, > > > > I am a beginner in Python programming.
