### 函数

| 函数名称 | 描述 |
| -------- | -------- |
| [OH_NativeImage_Create](_o_h___native_image.md#oh_nativeimage_create) (uint32_t textureId, uint32_t textureTarget) | 创建一个**OH_NativeImage**实例，该实例与OPENGL ES的纹理ID和纹理目标相关联. |
| [OH_NativeImage_AcquireNativeWindow](_o_h___native_image.md#oh_nativeimage_acquirenativewindow) (OH_NativeImage \*image) | 获取与OH_NativeImage相关联的OHNativeWindow指针. 该OHNativeWindow后续不再需要时需要调用 OH_NativeWindow_DestroyNativeWindow释放. |
| [OH_NativeImage_AttachContext](_o_h___native_image.md#oh_nativeimage_attachcontext) (OH_NativeImage \*image, uint32_t textureId) | 将OH_NativeImage实例附加到当前OPENGL ES上下文, 且该OPENGL ES纹理会绑定到 GL_TEXTURE_EXTERNAL_OES, 并通过OH_NativeImage进行更新. |
| [OH_NativeImage_DetachContext](_o_h___native_image.md#oh_nativeimage_detachcontext) (OH_NativeImage \*image) | 将OH_NativeImage实例从当前OPENGL ES上下文分离. |
| [OH_NativeImage_UpdateSurfaceImage](_o_h___native_image.md#oh_nativeimage_updatesurfaceimage) (OH_NativeImage \*image) | 通过OH_NativeImage获取最新帧更新相关联的OPENGL ES纹理. |
| [OH_NativeImage_GetTimestamp](_o_h___native_image.md#oh_nativeimage_gettimestamp) (OH_NativeImage \*image) | 获取最近调用OH_NativeImage_UpdateSurfaceImage的纹理图像的相关时间戳. |
| [OH_NativeImage_GetTransformMatrix](_o_h___native_image.md#oh_nativeimage_gettransformmatrix) (OH_NativeImage \*image, float matrix[16]) | 获取最近调用OH_NativeImage_UpdateSurfaceImage的纹理图像的变化矩阵. |
| [OH_NativeImage_Destroy](_o_h___native_image.md#oh_nativeimage_destroy) (OH_NativeImage \*\*image) | 销毁通过OH_NativeImage_Create创建的**OH_NativeImage**实例, 销毁后该 **OH_NativeImage**指针会被赋值为空. |
