2.3.4.2 Short Axis Image Flip
The Short-Axis Image Flip defines whether the input image is flipped across the short axis of the DMD. If this
parameter is changed while displaying a still image, re-send the input still image. If the image is not re-sent, the
output image might be slightly corrupted.
Figure 2-2 shows an example of a short axis image flip. In Structured
Light mode, the image flip takes effect on the next bit-plane, image, or video frame load.
