-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi All,
Attached is a patch, against svn, which adds ACO importing, and CSS color extraction, for the palette system. The ACO code only reads the version 1 section at the moment, I plan on finishing the version 2 support to extract color names a little later. Color spaces supported are RGB, CMYK, HSV and greyscale, but not Lab. The CSS import extracts colors defined in a .css file. If this patch meets the standards, perhaps someone would like to incorporate it into the repository. This patch would, I believe, enable the closing of Bug #316618 Thanks Nicola. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.6 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFGtMldG4yOusCUvb8RAvSVAJoD6KK24CPhq5AXsSzekqXUY3RF4wCfWDpw 5mUdq2GWEYX970J0gHzUWGE= =ZgvZ -----END PGP SIGNATURE-----
