yes, right. However GdkPixbufAnimation and its iter_advance() function 
will automatically restart the animation when the delay of the last 
frame has elapsed... that is, there's no way to avoid looping it currently.

right. I submitted a patch which adds _get_frame_count and 
_get_current_frame functions to GdkPixbufAnimation.


However, I've now another small conceptual problem now: consider the 
following code:

        printf("compiled against gdk-pixbuf %s\n", GDK_PIXBUF_VERSION);
        printf("linked against gdk-pixbuf %s\n\n", gdk_pixbuf_version);

if I dynamically link my program on my linux which has e.g. gdk-pixbuf 
version 2.10.3 installed, and then run that binary on another linux 
which has gdk-pixbuf 2.8 installed, will I get

compiled against gdk-pixbuf 2.10.3
linked against gdk-pixbuf 2.8.0

or rather:

compiled against gdk-pixbuf 2.10.3
linked against gdk-pixbuf 2.10.3

?

I think the first: i.e. gdk_pixbuf_version contains the version of the 
dynamically loaded library, but I just want to be sure...

Thanks,
Francesco Montorsi
