     like "png","jpg","bmp"  . . .
     If no extension is provided the "png" format is used by default

     Returns 1 in case of success,
             0 otherwise
     Note: this method may not produce the expected result been called
     ----  from the ROOT prompt by simple reason:
           The active window will be console window
           rather the last selected ROOT canvas.

                   The format is defined by the file name extension
                   like "png","jpg","bmp"  . . .
                   If no or some unknown extension is provided then
                   the "png" format is used by default
