Module tornado.api

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

Class ImageFloat

java.lang.Object

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

All Implemented Interfaces:

Serializable, PrimitiveStorage<FloatBuffer>, TornadoImagesInterface<FloatBuffer>

public final class ImageFloat
extends Object
implements TornadoImagesInterface<FloatBuffer>

ImageFloat relies on preview features of the Java platform:

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

Programs can only use ImageFloat when preview features are enabled.

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