### Function

# GdkPixbuf Pixbufnew_from_stream_at_scale_async

since: 2.24

#### Declaration [src]

    void
    gdk_pixbuf_new_from_stream_at_scale_async (
      GInputStream* stream,
      gint width,
      gint height,
      gboolean preserve_aspect_ratio,
      GCancellable* cancellable,
      GAsyncReadyCallback callback,
      gpointer user_data
    )

#### Description [src]

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.

Available since: 2.24
