 Note:
     The default rate control policy for colour images employs visual (CSF)
     weighting factors.  To minimize MSE instead, specify `-no_weights'.
 Note:
     If you want quality scalability, you should generate multiple layers
 with
     `-rate' or by using the "Clayers" option.

 Generated 6 tile-part(s) for a total of 6 tile(s).
 Code-stream bytes (excluding any file format) = 860,913 = 9.204537
