Class Java2DFrameConverter

java.lang.Object

org.bytedeco.javacv.FrameConverter<BufferedImage>

org.bytedeco.javacv.Java2DFrameConverter

public class Java2DFrameConverter
extends FrameConverter<BufferedImage>

A utility class to copy data between Frame and BufferedImage. Since BufferedImage does not support NIO buffers, we cannot share allocated memory with Frame.
