FYI, the following comments were taken out from http://www.linux-mag.com/id/2627/ __________________________ Normalizing high-contrast line art and graphics can be great. But normalized photos may look unreal, and, as was said earlier, may not print well either. The -contrast-stretch operator can limit the "boundaries" of the normalization, but the -levels and/or -sigmoidal-contrast operator can make "smoother" adjustments. __________________________ -- Tong (remove underscore(s) to reply) http://xpt.sf.net/techdocs/ http://xpt.sf.net/tools/ _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
