G'MIC Align layers, need help to get it work

Hi,

i try to use Align layers to align three misaligned photos, but i can’t get it to work.

Here is my workflow

  1. Load pictures as layers
  2. Open G’MIC QT -> Layers -> Align layers
  3. Set smoothness at minimum
  4. Input layers -> All
  5. Everything else left on default
  6. Preview shows aligned image
  7. Click OK, then there is processing for 5 seconds
  8. No aligment on my images

I try do do similar thing as Auto align layers in Photoshop does.
I also tried align_image_stack from Hugin, and it’s working perfectly. But i want to use one software if it’s possible.

So my question is, why is this plugin not working ? Is there some bug, or is there something what i need to do before or after this plugin is used ?

GIMP 2.10.12 , G’MIC 2.8.1 on Debian Testing

Thank you very much

That’s a quite old filter, maybe it needs revision.
Is it possible to have access to your images (maybe downscaled versions) ?

Thanks for your reply.

Here they are.

They are only for my testing, that’s why every image has different WB and is intentionaly misaligned. That way i can see if they are aligned when i set layer opacity to 50% :slight_smile:

Thanks

Thanks, that’s interesting.
When reducing the resolution (to 1024 px width) for a quick test, I got acceptable results with this filter. When I let the original resolution (6000 px width), it doesn’t work anymore.

I’ll check this later, but this seems to be a bug in this quite old (2010) filter.

Interesting :slight_smile:

Ok, i appreciate your help.

Thanks

Hello @David_Tschumperle

Just tried myself this plugin (G.MIC 2.8.0 with Gimp 2.10.14 on Windows 10).
I can not get it working either.
From its name I suppose I should get a new layer (or image) with all my layers aligned (stacked on top of each other)

Here is a Dropbox link with a ZIP folder with 3 jpeg images to align in case you need them for some more testing:

Btw, should i fill the bug report, or do you let me know when it will be fixed ?

No need to fill a bug report, I’m aware of the issue now :slight_smile:
Anyway, can’t say when it will be fixed.

Ok, no problem, just please let me know when it will be fixed.
Thanks

That should be fixed now, at least for the rigid alignment
(which is a bit misnamed, because it actually only manages translations, not scaling).

If you are using G’MIC 2.8.0+, just try the ‘Update filters’ button, and see if that works for you.
