From: Ivan Petrov <pravo@hnet.ru> To: community@lists.altlinux.org Subject: [Comm] djvu Date: Tue, 04 Nov 2008 14:52:28 +0600 Message-ID: <gep2gg$u5l$1@ger.gmane.org> (raw) 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? И.П.
