###### (This is the documentation for SDL3, which is the current stable version. [SDL2](https://wiki.libsdl.org/SDL2/) was the previous version!) # SDL_ChromaLocation Colorspace chroma sample location. ## Header File Defined in [](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_pixels.h) ## Syntax ```c typedef enum SDL_ChromaLocation { SDL_CHROMA_LOCATION_NONE = 0, /**< RGB, no chroma sampling */ SDL_CHROMA_LOCATION_LEFT = 1, /**< In MPEG-2, MPEG-4, and AVC, Cb and Cr are taken on midpoint of the left-edge of the 2x2 square. In other words, they have the same horizontal location as the top-left pixel, but is shifted one-half pixel down vertically. */ SDL_CHROMA_LOCATION_CENTER = 2, /**< In JPEG/JFIF, H.261, and MPEG-1, Cb and Cr are taken at the center of the 2x2 square. In other words, they are offset one-half pixel to the right and one-half pixel down compared to the top-left pixel. */ SDL_CHROMA_LOCATION_TOPLEFT = 3 /**< In HEVC for BT.2020 and BT.2100 content (in particular on Blu-rays), Cb and Cr are sampled at the same location as the group's top-left Y pixel ("co-sited", "co-located"). */ } SDL_ChromaLocation; ``` ## Version This enum is available since SDL 3.0.0. ---- [CategoryAPI](CategoryAPI), [CategoryAPIEnum](CategoryAPIEnum), [CategoryPixels](CategoryPixels)
