public class ImageTransfer extends ByteArrayTransfer
The classImageTransferprovides a platform specific mechanism for converting an Image represented as a javaImageDatato a platform specific representation of the data and vice versa.An example of a java
ImageDatais shown below:Image image = new Image(display, "C:\temp\img1.gif"); ImageData imgData = image.getImageData();- Since:
