Hi Lukas,
Thanks a lot indeed for this *HUGE* contribution to the Krita project! :-)
Did you manage to make it working the recolorize filter as well [0]?
IMHO, it would be really useful...
In addition, I am sure Animtim (and other painters) would be really happy to give it a try :-)
P.s: Yesterday, David Tschumperlé (aka Ronounours) has replied to the mail by Leinir [1] concering the patch for the Windows builds :-)
My best regards and keep rocking :-)

Oggetto: Re: GMIC in Krita
Testers are welcomed!I blacklisted all filters that crashed on my machine (it is semi-automatic process)so now we have 74% of filters confirmed as working. 26% of filters are blacklisted.Crashes are there most likely due to:a) bad parsing of gmic file formatb) missing features (multiple input / multiple output / unexpected output colorspace)Lukas2013/9/15 Paul Geraskin <paulgeraskin@gmail.com>
Super! Just let me know if you need a tester :-)15.09.2013 0:58 пользователь "Lukast dev" <lukast.dev@gmail.com> написал:
