     ZOOM SUBFORM

     The "Zoom On Image" subform allows you to zoom on the image.
     You may use the zoom box instead of the image to select
     clusters to be added to or deleted from a class category;
     you may also use the zoom box to transfer a cluster from one
     class category to another.  The "Zoom On Image" subform con-
     tains:

     A)  A float selection with which to change the zoom factor.
     B)  An action button labelled "Point & Click ZOOM", with
     which you initiate a zooming action.
     C)  The zoom box.
     D)  A position widget below the zoom box.

     Setting the Zoom Factor

     To set the zoom factor, simply enter the desired number in
     the parameter box of the float selection labelled, "Zoom
     Factor:".  Hitting <cr> will "set" the zoom factor.  The
     change in the zoom factor will be immediately reflected in
     the zoom box.

     Changing the Location of the Zoomed Image

     By default, the contents of the zoom box is a region in the
     exact middle of the image.  To change the contents of the
     zoom box, first click on the action button labelled "Point &
     Click ZOOM".  Then, click on the desired location within the
     image.  The location at which you click the mouse will
     become the exact center of the contents of the zoom box.

     Information Given by the Position Widget

     The position widget beneath the zoom box displays informa-
     tion in the form of "X x Y = Z", where [X x Y] is the loca-
     tion of the cursor in the image, and Z is the cluster number
     at that point.  This is true whether the cursor is in the
     image, or in the zoom box.

     HELP           Displays this help section.

     CLOSE          Exits the "Legend" subform and returns to the
                    main Spectrum subform.
