Solution
There is an IMAQ Symmetry function which can be obtained by downloading the NI-IMAQ driver. Using this function not only allows horizontal and vertical flips, but also allows central, 1st diagonal, and 2nd diagonal flips. If you downloaded the NI-IMAQ driver, you can find the IMAQ Symmetry function by right-clicking the block diagram and navigating to Vision and Motion>>Vision Utility>>Image Manipulation>>IMAQ Symmetry. The function is shown in Figure 1.
