Copy channel from one image to another image. - Krikor - 10-08-2020
How can I to copy channel from one image to another image?
I have two images open. In one of them I created channels which I want to use in the second image as well.
How I do:
I select one of the created channels - Channel for selection.
From this selection I create a path - Select - To Path.
In the Paths tab, drag this created path over the thumbnail of the second image.
I open the second image, and now I reverse the operation, select the path and create a channel from that selection.
Is there another, faster and more efficient way to copy channels from one layer to another?
Thank you.

A possible alternative - use "Open as Layers..." to open your second image within the first, then delete the layers of the first image, or make them non-visible.
This should leave your channels intact.

David, much better following your suggestion.
It would be nice to be able to copy the channels between the images as I copy the paths.
Thank you!

Make the source image active, open the Channels list, and drag the channel to the canvas of the target image.
This creates a layer in the target, so open the Channels list, and drag any of the R/G/B channels down to the Channels list to copy it. Once done you can remove the layer.
If you want to copy the selection; set both images to quickmask mode, Edit>Copy in source and Edit>Paste in target.

Thank you very much Ofnuts!

There is no Channels list (Windows>Dockable dialogs>Channels) in your Gimp?

I was referring to before seeing the tips here on the forum.
That I had found only part of the solution, but stopped when I pasted the copy onto the layer.
But after your tips everything was clarified.
Sorry for my pitiful English.
