You could use a full-screen quad to flip the image by changing the texture coordinates in DirectX. I.e. define 4 points with UV coordinates from 1.0 to 0.0 (instead of 0.0 to 1.0) to flip the image. Alternatively you can use dotNet to do it using Image.RotateFlip() with the appropriate param from System.Drawing.RotateFlipType
