Class ImageTransfer


  • public class ImageTransfer
    extends ByteArrayTransfer
    The class 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();
