public bool save_to_stream (OutputStream stream, string type, Cancellable? cancellable = null, ...) throws Error
Saves `pixbuf` to an output stream.
Supported file formats are currently "jpeg", "tiff", "png", "ico" or "bmp". See `gdk_pixbuf_save_to_buffer()` for more details.
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 at the end of this call.
