Examples
            See the example for IPUTDATA. 
            Syntax
        
            IGETDATA, ID, Arg1, Arg2, ... [, OBJECT=Value] [, TOOL=iToolID]
        
            Arguments
        
             ID
        
            A string containing the identifier of the iTools object from which to retrieve data. If you pass a partial identifier, the IGETID function is called to retrieve the full identifier string.
        
             Args         
            Named variables that will contain the returned data.         
            Keywords
        
            All other keywords are passed to the iTools object.         
            OBJECT
        
            Set this keyword to a named variable that will contain an object reference to the iTool visualization object specified by Id.
        
            TOOL
        
            Set this keyword to a string specifying one or more iTools in which to search for Id. If this keyword is not set, only the current iTool is searched.
        
            iTool Visualizations Compatible with IGETDATA
        
            IGETDATA can retrieve data from the following iTool visualizations:

                        | Colorbar | REDGREEN
 BLUE
 | Returns the color vectors from the contained palette. If only one argument is supplied, a 3xm array is returned. | 
                    
                        | Contour | Z, X, Y | Returns the Z, X, and Y arrays of data. | 
                    
                        | Image | DATA | Returns the image data. | 
                    
                        | Plot | [X], Y [, Z] | Returns Y (if one argument is supplied); X, Y (if two arguments are supplied); X, Y, Z (if three arguments are supplied and it is a 3D plot). | 
                    
                        | Plot3D | X [, Y] [, Z] | If Y and Z are not supplied, a 3xm array is returned in X. | 
                    
                        | Polygon | VERTICES | Returns a 3xm array of vertices in device coordinates. | 
                    
                        | Polyline | VERTICES | Returns a 3xm array of vertices in device coordinates. | 
                    
                        | Region of Interest (ROI) | VERTICES | Returns a 3xm array of vertices in device coordinates. | 
                    
                        | Surface | Z | Returns the surface as an mxn array. | 
                    
                        | Text | STRING | Returns a string containing the text displayed. | 
                    
                        | Vector | U, V, X, Y | Returns the U and V arrays, and the X and Y vectors. | 
                    
                        | Volume | VOL0VOL1
 VOL2
 VOL3
 | Returns the 3D volume arrays. |
