Upgrading fixed the problem, as you suggested. To get the upgrade, I added media-gfx/imagemagick to /etc/portage/package.keywords, so my system will now iupgrade to every new version of ImageMagick that has an ebuild. The last automatic upgrade I saw (January 26) was to version 6.2.5.5 to fix security bug #83542. I can't be sure from the ImageMagick ChangeLog that the security fix is also in 6.2.6.0. Am I worrying about nothing? Thanks again, John Green -- gentoo-user@gentoo.org mailing list
[gentoo-user] ImageMagick -contrast-stretch
Hi, The ImageMagick option -contrast-stretch is not recognised in my installation (6.2.5 01/31/06 Q16). The option is documented on the IM web-site. If the option exists on your installationi, or you have any insights, please reply here with your version, so I can decide whether and where to file a bug-report. You can do something like this: convert input.jpg -contrast-stretch 10% output.jpg Thanks. J Green -- gentoo-user@gentoo.org mailing list
