I use ImageMagick a LOT. Thanks for a great program. I use convert imagein -channel all -contrast-stretch 0x0 imageout on raw film scans to expand the histogram prior to gui editing. Sometimes I'd like to shrink/de-contrast an image. like convert imagein -channel all -contrast-stretch -1%%x-1%% imageout But negative arguments to -contrast-stretch seem to be ignored, with no complaint, and no effect on the image.
Can I achieve a contrast shrink some other way? TIA -- Russ Butler (NJ USA) _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
