For this kind of work I would use something like Gimp. Blending one image or color into another is described in books like "The Artist's Guide to Gimp Effects." a command line program like ImageMagick would be a bit clumsy for this task since the user is essentially working blind. The user of Open Source software should have an array of tools at hand, and not rely on one or two. I have on my computer and use IM, Gimp, Scribus, TeX and GVim. I have in reserve tools like Inkscape and Krita for tasks that may come up in the future. -- John Culleton Wexford Press "Create Book Covers with Scribus" Printable E-book 38 pages $5.95 http://www.booklocker.com/books/4055.html _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
