buffer_common.h

Overview

The buffer_common.h file declares the common types used in the NativeBuffer module.

Certain type definitions have been relocated from native_buffer.h to this header file for a more cohesive presentation. These types were available prior to API version 12 and can be used seamlessly across all versions.

Library: libnative_buffer.so

System capability: SystemCapability.Graphic.Graphic2D.NativeBuffer

Since: 12

Related module: OH_NativeBuffer

Summary

Structs

struct OH_NativeBuffer_ColorXY	Describes the X and Y coordinates of the primary color.
struct OH_NativeBuffer_Smpte2086	Describes the SMPTE ST 2086 static metadata.
struct OH_NativeBuffer_Cta861	Describes the CTA-861.3 static metadata.
struct OH_NativeBuffer_StaticMetadata	Describes the HDR static metadata.

Types

Name	Description
typedef enum OH_NativeBuffer_ColorSpace OH_NativeBuffer_ColorSpace	Defines an enum for the color spaces of an OH_NativeBuffer instance. It is relocated from native_buffer.h to this header file for a more cohesive presentation.
typedef enum OH_NativeBuffer_MetadataType OH_NativeBuffer_MetadataType	Defines an enum for the OH_NativeBuffer image standards.
typedef struct OH_NativeBuffer_ColorXY OH_NativeBuffer_ColorXY	Defines a struct for the X and Y coordinates of the primary color.
typedef struct OH_NativeBuffer_Smpte2086 OH_NativeBuffer_Smpte2086	Defines a struct for the SMPTE ST 2086 static metadata.
typedef struct OH_NativeBuffer_Cta861 OH_NativeBuffer_Cta861	Defines a struct for the CTA-861.3 static metadata.
typedef struct OH_NativeBuffer_StaticMetadata OH_NativeBuffer_StaticMetadata	Defines a struct for the HDR static metadata.
typedef enum OH_NativeBuffer_MetadataKey OH_NativeBuffer_MetadataKey	Defines an enum for the keys that specify the HDR metadata of an OH_NativeBuffer instance.
