Description:

[ CCode ( finish_name = "gdk_pixbuf_new_from_stream_finish" , has_construct_function = false , type = "void" ) ]
[ Version ( since = "2.24" ) ]
public async Pixbuf.from_stream_at_scale_async (InputStream stream, int width, int height, bool preserve_aspect_ratio, Cancellable? cancellable = null) throws Error

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

For more details see Pixbuf.from_stream_at_scale, 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 Pixbuf.from_stream_async.end to get the result of the operation.

Parameters:

stream	a `GInputStream` from which to load the pixbuf
width	the width the image should have or -1 to not constrain the width
height	the height the image should have or -1 to not constrain the height
preserve_aspect_ratio	`TRUE` to preserve the image's aspect ratio
cancellable	optional `GCancellable` object, `NULL` to ignore
callback	a `GAsyncReadyCallback` to call when the pixbuf is loaded
user_data	the data to pass to the callback function
