I used to use PIL, but switching to Cairo let me remove a dependency, and use the same API for drawing to the screen and drawing to image files. > 2) If the gtk.gdk.Pixbuf.get_pixels_array() or its internals are > deprecated, then what will replace it? I don't see a direct replacement. One way to do it is Pixbuf.save() to a PNG, then cairo.ImageSurface.create_from_png(). I don't know if that's significantly less efficient than Pixbuf.get_pixels_array(). It does avoid depending on NumPy. There might be useful information about this in the version control logs or bug tracker, if you're willing to dig for it. -- David Ripton [email protected] _______________________________________________ pygtk mailing list [email protected] http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
