        jpgsaveoptions = new jpegsaveoptions(); 

        jpgsaveoptions.embedcolorprofile = true; 

        jpgsaveoptions.formatoptions = formatoptions.standardbaseline; 

        jpgsaveoptions.matte = mattetype.none; 

        jpgsaveoptions.quality = jpegquality;  

        

        {

                activedocument.saveas(savefile, jpgsaveoptions, true, extension.lowercase);

                jpegquality--;
