Description Josselin Mouette 2009-06-17 08:17:39 UTC 
Original report from Luca Bruno: http://bugs.debian.org/525699

The documentation describes its usage using integers. More over, the method
doesn't seem to work correctly. Apparently, the alpha isn't added even using
chr(0), chr(0), chr(0).
>>> import gtk
>>> pixbuf = gtk.gdk.Pixbuf (gtk.gdk.COLORSPACE_RGB, True, 8, 100, 100)
>>> pixbuf.add_alpha (True, 0, 0, 0)
Traceback (most recent call last):

+ Trace 216044

  • File "<stdin>", line 1 in <module>
TypeError: GdkPixbuf.add_alpha() argument 2 must be char, not int

Comment 1 Paul Pogonyshev 2009-06-17 22:13:41 UTC 
Fixed, thanks.  The patch badly breaks backwards compatibility, but there is likely no code using this function anyway, as it seems pretty impossible to use in its pre-2.16 state.
