But after some googling I have found something that might help you: http://trac.bjourne.webfactional.com/ GtkImageViewer. It also comes with Python bindings. For the crop functionality, check the docs: http://trac.bjourne.webfactional.com/chrome/common/pygtkimageview-docs/ , there is a function ImageToolSelector (http://trac.bjourne.webfactional.com/chrome/common/pygtkimageview-docs/gtkimageview.ImageToolSelector-class.html) that can be customized to make an image cropper. Well, I hope my little finding can help. -- NOAGBODJI Paul Victor -- http://mail.python.org/mailman/listinfo/python-list
