Of course as IM can't generate a gradient image to match an existing image you can't use gradient: You can however use a -sparse-color operator to generate the gradient, with the right scale as it allows you to use percent escapes to set values. http://www.imagemagick.org/Usage/canvas/#barycentric convert -background None -size 100x \ caption:'A really long line generating a image of unknown height' \ \( +clone +matte \ -sparse-color Barycentric '0,0 White 0,%[fx:h-1] DodgerBlue' \ \) +swap -composite result.gif You can also use percent escapes in -distort arguments too! In the future some other arguments may also percent escapes, such as -size, (in which case you may be able to use 'gradient:' for the above instead) though this is as yet undecided. This is NOT a well published or exampled technique, and is still open to discussion by the ImageMagcik developers as to how usefull and wide spead this should become, especially as '%' is already a well known special flag for geometry-style arguments, which could cause confusion and problems. I would not rely on it. In fact the only other example is for the "Displaced Fractured Mirror" http://www.imagemagick.org/Usage/displace/#displace_mirror Anthony Thyssen ( System Programmer ) <[email protected]> ----------------------------------------------------------------------------- You said the learning curve was steep, but neglected to mention the roller coaster ride in the middle! -- Anni <[email protected]> ----------------------------------------------------------------------------- Anthony's Home is his Castle http://www.cit.gu.edu.au/~anthony/ _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
