How do I include basic image editing in my python application?

Question

I am making an application for the Ubuntu App Showdown and I want to include basic image editing like adding black and white, grey effects etc to the image. But I don't know how to do that. I have been reading about PIL and I have tried it and I can't get it to work. So if you could help me with an example or a link to tutorial or something else it would be very helpful. Thanks.

Answer 1

You can use Python Imaging Library (PIL), but you can also use Cairo. It also depends which graphical toolkit you're using for your app (GTK, Qt, something else...)

• PIL tutorials - here is one and here's another one that should help you get started
• PyGTK Cairo tutorial - a bit out of date, as Ubuntu 12.04 uses GTK3, and the tutorial is written for GTK2.

Answer 2

Another way to do image editing with Python is to write a script or plugin for the GIMP. Akkana Peck has some information about that in her GIMP book and the corresponding site.

But of course that might not fit in with your application...
