MODIFY/CUTS [image] [cursor_spec]
	modify cut values of full frame or in cursor selected windows
\us\pu
Purpose:
	  Interactively modify cut values of complete frame or within cursor
          selected windows of frame currently displayed.
\up\sy
Syntax:
          MODIFY/CUTS [image] [cursor_spec]
\ys\pa
          image = if given, this image will be loaded into the display
              window first;
\\
              otherwise the currently displayed image will be used
\ap\pa
          cursor_spec = character flag, either N(oCursor) or C(ursor) for
              modifying the cuts of the full displayed frame or on subframes
              of the displayed frame which are selected via the cursor
              rectangle;
\\
              defaulted to No (i.e. the full displayed frame)

Note: 
             In the `full frame mode' the histogram of the displayed frame
          is plotted in the graphics window.
\\
          With the graphics cursor choose the low and high cut values. These
          cuts are then used to reload the frame and you can choose again
          other cuts.
\\
          Pressing the EXIT button on the mouse (i.e. the right button)
          while in graphics cursor mode terminates the command. The descriptor
          LHCUTS(1,2) of the displayed frame is updated accordingly.
\\
             In the `cursor mode' you select a subframe via the cursor
          rectangle in the display window. The histogram of the selected
          subframe is plotted in the graphics window.
\\
          With the graphics cursor choose the low and high cut values. These
          cuts are then used to reload the subframe and you can choose again
          other cuts.
\\
          Pressing the EXIT button on the mouse (i.e. the right button)
          while in graphics cursor mode lets you move on to select other 
          subframes of the displayed frame.
\\
          Pressing the EXIT button on the mouse (i.e. the right button)
          in the display window when you select the subframes terminates 
          the command.
\\
          The last cut values specified are also stored in the real keyword
          OUTPUTR(1,2) in both modes.

Examples:
\ex
          MODIFY/CUTS 
            Modify the cut values of the currently displayed frame and
            update descr. LHCUTS.
\xe \ex
          MODIFY/CUTS ursula cursor
            Load image `ursula.bdf' and use the cursor rectangle to select
            subframes. Choose new cut values via the graphics cursor and
            reload the selected subframes. Save the last specified cut values
            in keyword OUTPUTR(1,2).
