    Image Editor allows you to create, design, modify or just inspect images.

    It is also used subclasses as a tool to post-process captured screen images and

    bitmaps in expecco.

    The actual drawing functionality is found in ImageEditView;

    the code here (an appModel) provides nice menus, previews, colormap manipulation etc.

    [start with:]

        ImageEditor open

        ImageEditor openOnClass:Icon andSelector:#startIcon

        (Image fromFile:'../../goodies/bitmaps/gifImages/garfield.gif') edit

        (Image fromScreen:(0@0 corner:100@100)) edit

    [see also:]

        ImageEditView Image
