Class Buffer

Espacio de nombres

easyar

Buffer almacena un raw byte array y puede usarse para acceder a image data. 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

Métodos

wrap

Envuelve 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.
