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