     IMAGE UTILITIES

     Through the "Image Utilities" pull-down menu, five of
     editimage's subforms can be accessed.  These subforms deal
     with input & output, regions of interest, colormaps, annota-
     tions, and miscellaneous image operations.

     1) Input/Output

     The first subform, "Input/Output", provides I/O capabilities
     for editimage.  Global input and output directories may be
     set using this subform. A new image may be input and
     displayed.  An image may be input so that the currently-
     displayed image may use the new image's colormap. An image
     may be provided to act as a clip mask or a shape mask.  An
     image may be overlaid onto the currently displayed image.
     Finally, images may be output from the "Input/Output" sub-
     form.

     2) Region of Interest

     The second subform, "Region of Interest", deals with region
     of interest operations. Such operations are useful for exe-
     cuting image processing routines on particular regions of an
     image. Using ROI functions, one is able to extract regions
     of an image, insert subimages into an image, and execute
     image processing routines on the region of interest.
     Regions of interest can be defined either by mouse or by
     keyboard.

     If the image has been converted in order to be displayed,
     ROI image processing routines will operate on the converted
     image data.  Also, in order for the image processing rou-
     tines to use any colormap changes that have been made, the
     image must first be saved and then that new image used for
     ROI manipulations.

     Warning: Application of image processing routines to a ROI
     voids all prior colormap operations, therefore the image
     should first be saved, otherwise the changes will be lost
     during this operation.  This occurs because RIO operations
     can create pixels with unknown LUT or colormap values,
     therefore the entire image is mapped according to a linear
     LUT.

     3) Colormaps

     The third subform, "Colormaps", contains standard colormaps
     through which the image pixel values can be automatically
     mapped.  Color can be changed using the following color
     schemes:

          RGB Cube
          RGB Triangle
          RGB Spiral (not available)
          RGB Distance
          CIE Diagram
          Density Slice
          Greyscale
          Original Colormap
          Rainbow
          Invert
          Random

     "Comment"

     4) Annotations

     The fourth subform, "Annotations", allows the user to add
     text, lines, circles, rectangles, or polygons to the
     displayed image.  Once created, objects may be deleted,
     copied, raised or lowered.  Using the COMBINE ANNOTATIONS
     action button found on the "Image Utilities" pulldown menu,
     annotations may actually be made part of the displayed
     image.

     4) Comment

     This subform may also be used to create or modify the com-
     ment on the image header of the currently displayed image.

     IMAGE INFO

     You may obtain information about the currently displayed
     image by using this button.

     COMBINE ANNOTATIONS

     If any annotations have been put onto the image using the
     "Annotations" subform, this button allows the user to actu-
     ally make the annotations part of the image.  Note that if
     an image with annotations is written out without using the
     COMBINE ANNOTATIONS button, the annotations will be lost!
