В перерывах между праздничным двиганием мебели :-))) :-(((( читаю man по 
  с44.
Вяыснил, что при сжатии в djvu с опцией -decibel 24,24,24,24 получается 
не слишком размыто, и файл поменьше.
Но тут прочитал еще опцию:

-dbfrac frac
Indicate that the decibel values specified in option -quality should be 
computed by averaging the mean squared errors of only the fraction frac 
of  the most  mis-represented  blocks of 32 x 32 pixels.  This option is 
useful with composite images containing solid color features (e.g. an 
image with a large white border).

Не понял, как ее использовать?
