a timeout (with g_timeout_add()) or by some other mechanism ensure

gdk_pixbuf_animation_iter_get_delay_time() milliseconds. Each time

the image is updated, you should reinstall the timeout with the new,

call gdk_pixbuf_animation_iter_advance().

If you're using #GdkPixbufLoader, in addition to updating the image

gdk_pixbuf_animation_iter_on_currently_loading_frame() returns

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

the frame itself. So your timeout should be reinstalled after any

<doc xml:space="preserve">The signature of a module is a set of prefixes. Prefixes are encoded as
|
||||
pairs of ordinary strings, where the second string, called the mask, if

not %NULL, must be of the same length as the first one and may contain
|
||||
' ', '!', 'x', 'z', and 'n' to indicate bytes that must be matched,
|
||||
not matched, "don't-care"-bytes, zeros and non-zeros.
|
||||
Each prefix has an associated integer that describes the relevance of
|
||||
the prefix, with 0 meaning a mismatch and 100 a "perfect match".
|
||||
|
||||
Starting with gdk-pixbuf 2.8, the first byte of the mask may be '*',
|
||||
indicating an unanchored pattern that matches not only at the beginning,
|
||||
but also in the middle. Versions prior to 2.8 will interpret the '*'
|
||||
like an 'x'.
|
||||
|
||||
The signature of a module is stored as an array of
|
||||
#GdkPixbufModulePatterns. The array is terminated by a pattern
|
||||
where the @prefix is %NULL.

of the loaded image is known.

|

The function is expected to set @width and @height to the desired
|
||||
size to which the image should be scaled. If a module has no efficient
|
||||
way to achieve the desired scaling during the loading of the image, it may
|
||||
either ignore the size request, or only approximate it - gdk-pixbuf will
|
||||
then perform the required scaling on the completely loaded image.
|
||||
|
||||
If the function sets @width or @height to zero, the module should interpret
|
||||
this as a hint that it will be closed soon and shouldn't allocate further
|
||||
resources. This convention is used to implement gdk_pixbuf_get_file_info()
|

efficiently.</doc>
