newFromStreamAtScaleAsync
fun newFromStreamAtScaleAsync(stream: <Error class: unknown class>, width: <Error class: unknown class>, height: <Error class: unknown class>, preserveAspectRatio: Boolean, cancellable: <Error class: unknown class>? = null, callback: <Error class: unknown class>?)
Creates a new pixbuf by asynchronously loading an image from an input stream.
For more details see gdk_pixbuf_new_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 gdk_pixbuf_new_from_stream_finish() to get the result of the operation.
