函数

名称 描述
OH_Image_Receiver_CreateImageReceiver (napi_env env, struct OhosImageReceiverInfo info, napi_value *res) 创建应用层 ImageReceiver 对象。
OH_Image_Receiver_InitImageReceiverNative (napi_env env, napi_value source) 通过应用层ImageReceiver对象初始化native层ImageReceiverNative对象。
OH_Image_Receiver_GetReceivingSurfaceId (const ImageReceiverNative *native, char *id, size_t len) 通过ImageReceiverNative获取receiver的id。
OH_Image_Receiver_ReadLatestImage (const ImageReceiverNative *native, napi_value *image) 通过ImageReceiverNative获取最新的一张图片。
OH_Image_Receiver_ReadNextImage (const ImageReceiverNative *native, napi_value *image) 通过ImageReceiverNative获取下一张图片。
OH_Image_Receiver_On (const ImageReceiverNative *native, OH_Image_Receiver_On_Callback callback) 注册一个OH_Image_Receiver_On_Callback回调事件。每当接收新图片，该回调事件就会响应。
OH_Image_Receiver_GetSize (const ImageReceiverNative *native, struct OhosImageSize *size) 通过ImageReceiverNative获取ImageReceiver的大小。
OH_Image_Receiver_GetCapacity (const ImageReceiverNative *native, int32_t *capacity) 通过ImageReceiverNative获取ImageReceiver的容量。
OH_Image_Receiver_GetFormat (const ImageReceiverNative *native, int32_t *format) 通过ImageReceiverNative获取ImageReceiver的格式。
OH_Image_Receiver_Release (ImageReceiverNative *native) 释放native层 ImageReceiverNative 对象。
