I have problems with some of my own filters. Most are original G'MIC filters I changed a bit. First I want to try to understand what's going on. I will check the original filters. there is a new color space. I know sequence is important in the code. Maybe that gives some errors too. (edit: it doesn't) So I first want to try to fix the errors myself. I can learn from that.
If there is a problem with a G'MIC filter, I will report it to you.
edit: At first sight, all filters work correct.
edit2: I now see that:
#@gimp Boost-fade : gimp_boost_fade, gimp_boost_fade_preview
#@gui Boost-fade : fx_boost_fade, fx_boost_fade_preview
-gimp_split_preview "-gimp_boost_chroma $*",$-1
-gui_split_preview "-fx_boost_chroma $*",$-1
Now I have almost all my own filters working.
