Struct gdk_pixbuf::PixbufAnimation[][src]

pub struct PixbufAnimation(_);
Expand description

An opaque struct representing an animation.

Implements

PixbufAnimationExt

Implementations

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 with a reference count of 1, or None if any of several error conditions ocurred: the file could not be opened, there was no loader for the file’s format, there was not enough memory to allocate the image buffer, or the image file contained invalid data.

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

The file format is detected automatically. If None is returned, then error will be set.

resource_path

the path of the resource file

Returns

A newly-created animation, or None if any of several error conditions occurred: the file could not be opened, the image format is not supported, there was not enough memory to allocate the image buffer, the stream contained invalid data, or the operation was cancelled.

Creates a new animation by loading it from an input stream.

The file format is detected automatically. If None 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 gio::InputStream to load the pixbuf from

cancellable

optional gio::Cancellable object, None to ignore

Returns

A newly-created pixbuf, or None if any of several error conditions occurred: the file could not be opened, the image format is not supported, there was not enough memory to allocate the image buffer, the stream contained invalid data, or the operation was cancelled.

Creates a new animation by asynchronously loading an image from an input stream.

For more details see Pixbuf::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 gio::InputStream from which to load the animation

cancellable

optional gio::Cancellable object, None to ignore

callback

a GAsyncReadyCallback to call when the pixbuf is loaded
