easyar

Buffer는 raw byte array를 저장하며 image data에 접근하는 데 사용할 수 있습니다. In the Java API, you can get the buffer from Image and then copy data to a Java byte array. In all versions of EasyAR Sense, you can access image data. Refer to Image.

Buffer

메서드

wrap

래핑합니다 a raw memory block of a specified length. When Buffer is fully released, the deleter callback is called to execute user-defined memory destruction behavior. deleter must be thread-safe.
