pub struct PixbufAnimation { /* private fields */ }
Expand description
An opaque object representing an animation.
The GdkPixBuf library provides a simple mechanism to load and represent animations. An animation is conceptually a series of frames to be displayed over time.
The animation may not be represented as a series of frames internally; for example, it may be stored as a sprite and instructions for moving the sprite around a background.
To display an animation you don’t need to understand its
representation, however; you just ask Pixbuf
what should
be displayed at a given point in time.

Implementations§
Source§impl PixbufAnimation
impl PixbufAnimation
pub const NONE: Option<&'static PixbufAnimation> = None
Sourcepub fn from_file(filename: impl AsRef<Path>) -> Result<PixbufAnimation, Error>
pub fn from_file(filename: impl AsRef<Path>) -> Result<PixbufAnimation, Error>
Creates a new animation by loading it from a file.
The file format is detected automatically.
If the file’s format does not support multi-frame images, then an animation with a single frame will be created.
Possible errors are in the GDK_PIXBUF_ERROR
and G_FILE_ERROR
domains.
§filename
Name of file to load, in the GLib file name encoding
§Returns
A newly-created animation
Sourcepub fn from_resource(resource_path: &str) -> Result<PixbufAnimation, Error>
pub fn from_resource(resource_path: &str) -> Result<PixbufAnimation, Error>
Sourcepub fn from_stream(
stream: &impl IsA<InputStream>,
cancellable: Option<&impl IsA<Cancellable>>,
) -> Result<PixbufAnimation, Error>
pub fn from_stream( stream: &impl IsA<InputStream>, cancellable: Option<&impl IsA<Cancellable>>, ) -> Result<PixbufAnimation, Error>
Creates a new animation by loading it from an input stream.
The file format is detected automatically.
If NULL
is returned, then @error will be set.
The @cancellable can be used to abort the operation from another thread.
If the operation was cancelled, the error G_IO_ERROR_CANCELLED
will be
returned. Other possible errors are in the GDK_PIXBUF_ERROR
and
G_IO_ERROR
domains.
The stream is not closed.
§stream
a GInputStream
to load the pixbuf from
§cancellable
optional GCancellable
object
§Returns
A newly-created animation
Sourcepub fn from_stream_async<P: FnOnce(Result<PixbufAnimation, Error>) + 'static>(
stream: &impl IsA<InputStream>,
cancellable: Option<&impl IsA<Cancellable>>,
callback: P,
)
pub fn from_stream_async<P: FnOnce(Result<PixbufAnimation, Error>) + 'static>( stream: &impl IsA<InputStream>, cancellable: Option<&impl IsA<Cancellable>>, callback: P, )
Creates a new animation by asynchronously loading an image from an input stream.
For more details see gdk_pixbuf_new_from_stream(), which is the synchronous version of this function.
When the operation is finished, callback
will be called in the main thread.
You can then call gdk_pixbuf_animation_new_from_stream_finish() to get the
result of the operation.
§stream
a #GInputStream from which to load the animation
§cancellable
optional #GCancellable object
§callback
a GAsyncReadyCallback
to call when the pixbuf is loaded
pub fn from_stream_future( stream: &(impl IsA<InputStream> + Clone + 'static), ) -> Pin<Box_<dyn Future<Output = Result<PixbufAnimation, Error>> + 'static>>
