• Changed state: Accepted
• Added labels: Priority-High
• Removed labels: Priority-Medium

from openjpeg.

Following the norm, each tile-component can be coded with is own transformation 
(reversible or irreversible) so is quite difficult to have one unique function: 
cf markers COD and COC

Funky one:
$ kdu_compress -no_info -i lena512.pgm -o lena512.j2k Ckernels:T2C0=W9X7 
"Stiles={256,256}" Ckernels:T1C0=W5X3

More fun:
$ kdu_compress -no_info -i lena512.pgm -o lena512.j2k Ckernels:T2C0=W9X7 
"Stiles={256,256}" Ckernels:T1C0=W5X3 Clevels:T1C0=0 Cuse_sop:T2=yes 
Cprecincts:T0="{128,128}"
