Summary

Structs

Name	Description
struct ColorSpacePrimaries	Describes the color space primaries.
struct WhitePointArray	Describes a white point array. Each white point indicates the coordinates of white in the active color space.

Types

Name	Description
typedef struct OH_NativeColorSpaceManager OH_NativeColorSpaceManager	Provides the declaration of an OH_NativeColorSpaceManager struct.
typedef enum ColorSpaceName ColorSpaceName	Defines an enum for the color space names.
typedef struct ColorSpacePrimaries ColorSpacePrimaries	Provides the declaration of a ColorSpacePrimaries struct.
typedef struct WhitePointArray WhitePointArray	Defines a struct for a white point array. Each white point indicates the coordinates of white in the active color space.

Functions

Name	Description
OH_NativeColorSpaceManager * OH_NativeColorSpaceManager_CreateFromName (ColorSpaceName colorSpaceName)	Creates an OH_NativeColorSpaceManager instance based on a color space name. A new OH_NativeColorSpaceManager instance is created each time this function is called.
OH_NativeColorSpaceManager * OH_NativeColorSpaceManager_CreateFromPrimariesAndGamma (ColorSpacePrimaries primaries, float gamma)	Creates an OH_NativeColorSpaceManager instance based on the color primaries and gamma value. A new OH_NativeColorSpaceManager instance is created each time this function is called.
void OH_NativeColorSpaceManager_Destroy (OH_NativeColorSpaceManager *nativeColorSpaceManager)	Destroys an OH_NativeColorSpaceManager instance.
int OH_NativeColorSpaceManager_GetColorSpaceName (OH_NativeColorSpaceManager *nativeColorSpaceManager)	Obtains the color space name.
WhitePointArray OH_NativeColorSpaceManager_GetWhitePoint (OH_NativeColorSpaceManager *nativeColorSpaceManager)	Obtains the white points.
float OH_NativeColorSpaceManager_GetGamma (OH_NativeColorSpaceManager *nativeColorSpaceManager)	Obtains the gamma value.
