Create a new GdkPixbuf.PixbufAnimation

Parameters:

Object properties

Create a new GdkPixbuf.PixbufAnimation

Parameters:

String filename Required (not null)

Returns:

GdkPixbuf.PixbufAnimation

Queries the height of the bounding box of a pixbuf animation.

Returns:

Number

Get an iterator for displaying an animation. The iterator provides the frames that should be displayed at a given time. It should be freed after use with g_object_unref(). marks the beginning of animation playback. After creating an iterator, you should immediately display the pixbuf returned by gdk_pixbuf_animation_iter_get_pixbuf(). Then, you should install a timeout (with g_timeout_add()) or by some other mechanism ensure that you'll update the image after gdk_pixbuf_animation_iter_get_delay_time() milliseconds. Each time the image is updated, you should reinstall the timeout with the new, possibly-changed delay time. As a shortcut, if start_time is NULL, the result of g_get_current_time() will be used automatically. To update the image (i.e. possibly change the result of gdk_pixbuf_animation_iter_get_pixbuf() to a new frame of the animation), call gdk_pixbuf_animation_iter_advance(). If you're using GdkPixbufLoader, in addition to updating the image after the delay time, you should also update it whenever you receive the area_updated signal and gdk_pixbuf_animation_iter_on_currently_loading_frame() 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. So your timeout should be reinstalled after any area_updated signal. A delay time of -1 is possible, indicating "infinite."

Parameters:

GLib.TimeVal start_time Required (not null)

Returns:

GdkPixbuf.PixbufAnimationIter

If an animation is really just a plain image (has only one frame), this function returns that image. If the animation is an animation, this function returns a reasonable thing to display as a static unanimated image, which might be the first frame, or something more sophisticated. If an animation hasn't loaded any frames yet, this function will return NULL.

Returns:

GdkPixbuf.Pixbuf

Queries the width of the bounding box of a pixbuf animation.

Returns:

Number

If you load a file with gdk_pixbuf_animation_new_from_file() and it turns out to be a plain, unanimated image, then this function will return TRUE. Use gdk_pixbuf_animation_get_static_image() to retrieve the image.

Returns:

Boolean
