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

source

pub const NONE: Option<&'static PixbufAnimation> = None

source

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

source

pub fn from_resource(resource_path: &str) -> Result<PixbufAnimation, Error>

Creates a new pixbuf animation by loading an image from an resource.

The file format is detected automatically. If NULL is returned, then @error will be set.

resource_path

the path of the resource file

Returns

A newly-created animation

source

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

source

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

source

pub fn from_stream_future( stream: &(impl IsA<InputStream> + Clone + 'static) ) -> Pin<Box_<dyn Future<Output = Result<PixbufAnimation, Error>> + 'static>>
