Possibly advances an animation to a new frame. Chooses the frame based on the start time passed to gdk_pixbuf_animation_get_iter(). must be greater than or equal to the time passed to gdk_pixbuf_animation_get_iter(), and must increase or remain unchanged each time gdk_pixbuf_animation_iter_get_pixbuf() is called. That is, you can't go backward in time; animations only play forward. As a shortcut, pass NULL for the current time and g_get_current_time() will be invoked on your behalf. So you only need to explicitly pass at double speed. If this function returns FALSE, there's no need to update the animation display, assuming the display had been rendered prior to advancing; if TRUE, you need to call gdk_animation_iter_get_pixbuf() and update the display with the new pixbuf.

Parameters:

GLib.TimeVal current_time Required (not null)

Returns:

Boolean

Gets the number of milliseconds the current pixbuf should be displayed, or -1 if the current pixbuf should be displayed forever. g_timeout_add() conveniently takes a timeout in milliseconds, so you can use a timeout to schedule the next update.

Returns:

Number

Gets the current pixbuf which should be displayed; the pixbuf will be the same size as the animation itself (gdk_pixbuf_animation_get_width(), gdk_pixbuf_animation_get_height()). This pixbuf should be displayed for gdk_pixbuf_animation_iter_get_delay_time() milliseconds. The caller of this function does not own a reference to the returned pixbuf; the returned pixbuf will become invalid when the iterator advances to the next frame, which may happen anytime you call gdk_pixbuf_animation_iter_advance(). Copy the pixbuf to keep it (don't just add a reference), as it may get recycled as you advance the iterator.

Returns:

GdkPixbuf.Pixbuf

Used to determine how to respond to the area_updated signal on GdkPixbufLoader when loading an animation. area_updated is emitted for an area of the frame currently streaming in to the loader. So if you're on the currently loading frame, you need to redraw the screen for the updated area.

Returns:

Boolean
