MODIFY/ITT [method] [value] [prflag]
	modify the currently active ITT
\us\pu
Purpose:  
          Modify the currently active intensity transfer table (ITT).
\up\sy
Syntax: 
          MODIFY/ITT [method] [value] [prflag]
\ys\pa
          method = BAND, for overlaying a one value band on the ITT 
\\
                 = ROTATE, for rotating the offset of the ITT
\\
                 = SQEEZE, for squeezing/stretching of the ITT
\\
                 = CONVOLVE, for convolving it with another ITT 
\\
                 = CONTRAST, for contrast stretching;
\\
                 defaulted to BAND
\ap\pa
          value = value we want to use for method BAND, in [0,255];
\\
                  defaulted to 255 for BAND;
\\
                = CONT or NO, for method CONVOLVE, for continuous convolution
                  or not; defaulted to NO for CONVOLVE
\ap\pa
          prflag = only used for method BAND:
\\
            Y(es) or N(o) for displaying the intensity interval corrsponding to
            the chosen band, defaulted to No

Note: 
          Use the joystick (or arrow keys for X11) to modify the ITT(s).
          To terminate, set cursor \#1 to off and press ENTER (or press the
          exit button of the mouse in X11).
\\
          If invalid method or value is entered, the defaults are taken.
\\
          Method "CONVOLVE" does not use the cursor, instead the name of the
          ITT table to convolve the current ITT with is asked for.
\\
          For method ROTATE you must start rotating towards the right.
\\
          To save your new, modified LUT use the command GET/LUT which will
          create a copy of the current LUT in MID_WORK.

Examples:
\ex
          MODIFY/ITT BAND 88
            Put a band with pixel value 88 over current ITT.
