As far as I can tell, for JPEG files, by setting -quality 70-100, the filesize and its quality change won't be noticeable. However, if you lower more JPEG's "-quality", we might get smaller filesize but there should be some "perceptional" loss. The OP may be interested in "-quantize" option and test the images with his output devices( LCD?, Mobile?, PDA or iPhone?) -- Best Regards, Nguyen Hung Vu ( Nguyễn Vũ Hưng ) [EMAIL PROTECTED] , YIM: vuhung16 , Skype: vuhung16dg A brief profile: http://www.hn.is.uec.ac.jp/~vuhung/Nguyen.Vu.Hung.html _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
