… accessed from Python. Creating a new function gimp_value_array_get_color_array(). This should normally not be needed (it isn't in C), but because of GObject Introspection limitation and the fact that pygobject will automatically try to convert GValue to the embedded value, we get this weird situation where the result is unusable in Python for certain types. One of these types is GimpColorArray. I suggest an annotation request to GObject Introspection: https://gitlab.gnome.org/GNOME/gobject-introspection/-/issues/492 I think that with such annotation, followed as a second step by pygobject support, correctly handling NULL terminated C arrays generically should be feasible by bindings.
