Package uk.ac.manchester.tornado.api.types.images

Class ImageByte4

java.lang.Object

uk.ac.manchester.tornado.api.types.images.ImageByte4

All Implemented Interfaces:

Serializable, PrimitiveStorage<ByteBuffer>, TornadoImagesInterface<ByteBuffer>

public final class ImageByte4
extends Object
implements TornadoImagesInterface<ByteBuffer>

ImageByte4 relies on preview features of the Java platform:

• ImageByte4 refers to one or more preview APIs: MemorySegment.

Programs can only use ImageByte4 when preview features are enabled.

Preview features may be removed in a future release, or upgraded to permanent features of the Java platform.
