""""""""""

*Namespace:* ``P1.CameraSdk``

Request a full IIQ file of the image

.. ref-code-block:: csharp
	:class: doxyrest-overview-code-block

    public void RequestImageAsync();

This method triggers on-demand transfer of the entire IIQ file of an image. To retrieve the object, you must listen for the :ref:`EventType.CameraImageReady <doxcsid-class_p1_1_1_camera_sdk_1_1_event_type_1aca2da860f6c08f098b8e16be9dae6295>` notification, *before* calling this method. This notification contains the image via the :ref:`INotificationEvent.FullImage <doxcsid-interface_p1_1_1_camera_sdk_1_1_i_notification_event_1a06b31db4984a9561244807f6b85872b2>` method.

The listener thread cannot know whether the arrived image is a just triggered capture, or a result of an on-demand request from this method. Therefore, use the IIQ filename to identify your requested image.

You *must* subscribe to image transfers via :ref:`IFullImageSubscription <doxcsid-interface_p1_1_1_camera_sdk_1_1_i_full_image_subscription>` for any images to be transferred.
