{{{
C:\>kdu_compress.exe -i test.bmp -o prec3.jp2 Creversible=yes
Cprecincts={128,128} Stiles={71,393}
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 33 tile-part(s) for a total of 33 tile(s).
Code-stream bytes (excluding any file format) = 758,998 = 8.114903
bits/pel.
Layer bit-rates (possibly inexact if tiles are divided across tile-parts):
8.114903
Layer thresholds:
0
Processed using the multi-threaded environment, with
8 parallel threads of execution
