Class Java2DFrameUtils

java.lang.Object

org.bytedeco.javacv.Java2DFrameUtils

public class Java2DFrameUtils
extends Object

Convenience class for performing various conversions between Mat, IplImage, BufferedImage and Frame objects. Methods are synchronized because the underlying JavaCV converters aren't safe for concurrent access. All created Frame, Mat, IplImages and BufferedImages are cloned internally after creation so that their memory locations remain valid after the converters which created them are closed or garbage collected. This is safer for the caller, but may be slower. If performance is critical, use the *FrameConverter classes directly, after reading about the image validity constraints (eg, images data is only valid until next call to the converter).

Method Detail

deepCopy

public static BufferedImage deepCopy(BufferedImage source)
