I can't tell what you mean. Do you mean to take a snapshot of an existing pixbuf, convert that snapshot to grayscale, and display the snapshot over the existing pixbuf? If so, the easiest way I know of is gtk.gdk.Pixbuf.get_pixels_array and gtk.gdk.pixbuf_new_from_array [1]. These methods allow you to do math on the pixels as a Numeric Python array, and then make a new Pixbuf from the resulting array. 1. http://www.pygtk.org/docs/pygtk/class-gdkpixbuf.html#method-gdkpixbuf--get-pixels-array -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFHKmkCUJT6e6HFtqQRAgrjAJ47VHqmT9j7xVAyNzgKXdgDTxQWMQCffJ6k D26RDImuualfzAdlJNaP4k0= =Oc7S -----END PGP SIGNATURE----- _______________________________________________ Sugar mailing list [email protected] http://lists.laptop.org/listinfo/sugar
