Data Structures

struct  AVLumaCoefficients
 Struct containing luma coefficients to be used for RGB to YUV/YCoCg, or similar calculations. More...
struct  AVCIExy
 Struct containing chromaticity x and y values for the standard CIE 1931 chromaticity definition. More...
struct  AVPrimaryCoefficients
 Struct defining the red, green, and blue primary locations in terms of CIE 1931 chromaticity x and y. More...
struct  AVColorPrimariesDesc
 Struct that contains both white point location and primaries location, providing the complete description of a color gamut. More...


typedef AVCIExy AVWhitepointCoefficients
 Struct defining white point location in terms of CIE 1931 chromaticity x and y. More...
typedef double(* av_csp_trc_function) (double)
 Function pointer representing a double -> double transfer function that performs an EOTF transfer inversion. More...


const AVLumaCoefficientsav_csp_luma_coeffs_from_avcsp (enum AVColorSpace csp)
 Retrieves the Luma coefficients necessary to construct a conversion matrix from an enum constant describing the colorspace. More...
const AVColorPrimariesDescav_csp_primaries_desc_from_id (enum AVColorPrimaries prm)
 Retrieves a complete gamut description from an enum constant describing the color primaries. More...
enum AVColorPrimaries av_csp_primaries_id_from_desc (const AVColorPrimariesDesc *prm)
 Detects which enum AVColorPrimaries constant corresponds to the given complete gamut description. More...
double av_csp_approximate_trc_gamma (enum AVColorTransferCharacteristic trc)
 Determine a suitable 'gamma' value to match the supplied AVColorTransferCharacteristic. More...
av_csp_trc_function av_csp_trc_func_from_id (enum AVColorTransferCharacteristic trc)
 Determine the function needed to apply the given AVColorTransferCharacteristic to linear input. More...
