Horizontal Mirror Flip function -does one exist in Warp and Blend API

I’m working on a display setup where one display needs to be horizontally mirror flipped (i.e. text reads backwards). (I’m outputting to 2 external displays with a Quadro RTX 5000 laptop card in discrete mode). In the description page about the Warp & Blend API I see this: “Apply warping to any scenario that requires image geometry corrections such as rotation, skew, mirroring, offset, and geometry mapping.”

In the NVAPI, however, I searched and couldn’t easily find a function which would do mirroring. Does anyone have any experience with implementing mirror flips? It seems it should be a common need, for instance if projecting with a mirror.
