Description animtim 2014-06-25 10:45:54 UTC

When I use Image-> Separate Image action, I keep all default settings except I select "output to color, not grayscale".
Then on each of the resulting C,M,Y,K layers I activate only the respective color channel flag and disable all the others (so Cyan has only cyan channel activated, etc..)

So it would be very time-saving to have an option to do this automatically in the Separate Image window.

Note that I use to uncheck alpha channel too and add a white background layer behind, but that's not really necessary in most cases.

Reproducible: Always

Make Separate Channels work again

* This removes the code for saving the separations to files. This
has been disabled since 2006
* Fixes adding the layers (this was broken because the progress
reporter was set to 100 before adding the layers, which means that
iterrupted() was true, so the layers were never added)
* Fixes unlocking the image (which happened inside the block that
added nodes, which wasn't executed because of see above)
* And makes it possible to only activate the relevant channel when
separating to color
