ROP effects are raster operation effects, which run in real-time either on the FALCON/EAGLE board or on the VGA card.
Image reflection around the horizontal axle
During image acquisition FALCON/EAGLE can mirror an image in real time on the horizontal axis independent of working in capture or display mode. In steal mode you can choose whether image mirroring should be done with image displayed on screen and/or image in main memory.
