It should be freed after use with 'GI.GObject.Objects.Object.objectUnref'. /@startTime@/ would normally come from 'GI.GLib.Functions.getCurrentTime', and marks the beginning of animation playback. After creating an iterator, you should immediately display the pixbuf returned by 'GI.GdkPixbuf.Objects.PixbufAnimationIter.pixbufAnimationIterGetPixbuf'. Then, you should install a timeout (with @/g_timeout_add()/@) or by some other mechanism ensure that you\'ll update the image after 'GI.GdkPixbuf.Objects.PixbufAnimationIter.pixbufAnimationIterGetDelayTime' milliseconds. Each time the image is updated, you should reinstall the timeout with the new, possibly-changed delay time.

To update the image (i.e. possibly change the result of 'GI.GdkPixbuf.Objects.PixbufAnimationIter.pixbufAnimationIterGetPixbuf' to a new frame of the animation), call 'GI.GdkPixbuf.Objects.PixbufAnimationIter.pixbufAnimationIterAdvance'. If you\'re using 'GI.GdkPixbuf.Objects.PixbufLoader.PixbufLoader', in addition to updating the image after the delay time, you should also update it whenever you receive the area_updated signal and 'GI.GdkPixbuf.Objects.PixbufAnimationIter.pixbufAnimationIterOnCurrentlyLoadingFrame' returns 'True'. In this case, the frame currently being fed into the loader has received new data, so needs to be refreshed. The delay time for a frame may also be modified after an area_updated signal, for example if the delay time for a frame is encoded in the data after the frame itself.
