format  void MPG_WnSetSize (MpgWn mpgwn, Uint32 dsx, Uint32 dsy)
 Input  mpgwn: MPEG window
:  dsx: Size in X direction (pixel unit)
:  dsy: Size in Y direction (pixel unit)
 Output  None
 Function value  None
 Function  Sets the display window size. If the window is open,
  The display size will be changed immediately.

  format  void MPG_WnSetDispOfst (MpgWn mpgwn, Sint32 dlx, Sint32 dly)
 Input  mpgwn: MPEG window
:  dlx: Display relative position in X direction (pixel unit)
:  dly: Display relative position in Y direction (pixel unit)
 Output  None
 Function value  None
 Function  Sets the display relative position of the display window.
.  Refer to “5. MPEG Window” for details. 

  format  void MPG_WnSetDispRatio (MpgWn mpgwn, Uint32 x_rat, Uint32 y_rat)
 Input  mpgwn: MPEG window
 x  x_rat: magnification in X direction (fixed point format)
 Y  Y_rat: magnification in the Y direction (fixed point format)
 Output  None
 Function value  None
 Function  Sets the magnification of the frame buffer window relative to the display window.
.  You can zoom in / out by gradually changing this value.
  The actual magnification is calculated using the following formula.
 
 
 
 X direction: x_rat / 1000
 Y direction: y_rat / 1000
