Thank you for your feedback. I have only read some papers about how
SIOX extract thing, and didn't sure the real lack point of SIOX. Your
suggestion is very helpful. :)

I didn't read the code of SIOX and GIMP yet, and be not sure if the
features in this page <http://www.siox.org/preview.html> has been
implemented in GIMP's current development version. If not, is it a
good a GSoC project of implementing these features? And I'm still not
sure if Gerald want to be a mentor in this GSoC Season.

BTW, I have idled on the IRC channel #gimp for days, where I'm glad if
anyone could give me suggestions, or just talk :)


Cheers,
Jenny
