| - | M.B. this does **not** take into account the fact that different chroma components contribute differently to the luma of the pixel. A more correct implementation must first separate luma and chroma, perform rotation on chroma, and then convert back to RGB triplet | + | M.B. this does **not** take into account the fact that different chroma components contribute differently to the luma of the pixel. A more correct implementation must first separate luma and chroma, perform rotation on chroma, and then convert back to RGB triplet, but that is way too expensive to perform in-line during video transmission. |
