+and Rotating an External Surface</title><shortdesc>This topic provides an example of flipping and rotating a surface
+in order to mirror the camera viewfinder during video telephony. </shortdesc><prolog><metadata><keywords/></metadata></prolog><conbody>
+<p> <b>Variant</b>: ScreenPlay. <b>Target audience</b>: Device
+creators. </p>
+<p>When users use the camera at the front of their phone during video telephony,
+they expect their image to be mirrored like when they look in a mirror. The
+camera viewfinder renders its content to a graphics surface which is displayed
+in a window by setting it as the background surface. To mirror the viewfinder
+content, first flip the surface and then rotate it by 180°. </p>

+<p>The following example code assumes that the surface already exists. Call <xref href="GUID-59A10068-E37A-37CF-85C9-36D8DA6619FA.dita#GUID-59A10068-E37A-37CF-85C9-36D8DA6619FA/GUID-F42D5405-2144-34AB-B3FE-C1D76C2A3B31"><apiname>TSurfaceConfiguration::SetFlip()</apiname></xref> to
+flip the surface, then call <xref href="GUID-59A10068-E37A-37CF-85C9-36D8DA6619FA.dita#GUID-59A10068-E37A-37CF-85C9-36D8DA6619FA/GUID-A7CC9BAA-301D-3006-AAA8-6549B163A448"><apiname>TSurfaceConfiguration::SetOrientation()</apiname></xref> to
+rotate the flipped surface by 180°. Finally bind the surface to the window.
+If necessary, set attributes such as extent to the surface configuration. </p>
