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();
