# SDL_MatrixCoefficients

The matrix coefficients.

## Header File

Defined in [<SDL3/SDL_pixels.h>](https://github.com/libsdl-org/SDL/blob/main/include/SDL3/SDL_pixels.h)

## Syntax

```c

    SDL_MATRIX_COEFFICIENTS_BT709 = 1,              /**< ITU-R BT.709-6 */
    SDL_MATRIX_COEFFICIENTS_UNSPECIFIED = 2,
    SDL_MATRIX_COEFFICIENTS_FCC = 4,                /**< US FCC */
    SDL_MATRIX_COEFFICIENTS_BT470BG = 5,            /**< ITU-R BT.470-6 System B, G / ITU-R BT.601-7 625, functionally the same as SDL_MATRIX_COEFFICIENTS_BT601 */
    SDL_MATRIX_COEFFICIENTS_BT601 = 6,              /**< ITU-R BT.601-7 525 */
    SDL_MATRIX_COEFFICIENTS_SMPTE240 = 7,           /**< SMPTE 240M */

    SDL_MATRIX_COEFFICIENTS_BT2020_NCL = 9,         /**< ITU-R BT.2020-2 non-constant luminance */
    SDL_MATRIX_COEFFICIENTS_BT2020_CL = 10,         /**< ITU-R BT.2020-2 constant luminance */
    SDL_MATRIX_COEFFICIENTS_SMPTE2085 = 11,         /**< SMPTE ST 2085 */
