2-Alternatives:
Triplicate into three layers and apply Colors -> Components -> Extract Component (GEGL) for each of C, M , Y in turn. Key is still broken and returns a black layer.
3-Steal the two plugins compose / decompose from a Gimp 2.8 installation for use in Gimp 2.10.
1-Yep ... I checked the report. Done 6 months ago. :-(
2-Yes, there seems to be no other way. Unfortunately, the K channel has no salvation.
I would like to use PatDavid's script that decomposes a color image to channels using various decomposition methods. (RGB, Value, Lightness, CMY, (cmy) K, L (ab), Luma).
But with this bug, the script generates 5 channels (RGB, HSL-L and HSV-V) and then crashes.
3-I started using Gimp from version 2.10.01. To get these 2 plugins or I would have to download a Gimp 2.8 or rely on the generosity of others.
Rich2005, thank you so much! At least I know that my Gimp is not the reason for the problem.
