Hi Ofnuts, i have a request. :oops:

I'm sure that you remember this topic http://www.gimptalk.com/index.php?/topi ... te-layers/
I have a file image.xcf with 100 layers, i manually subdivide all layers:
Layer2-Layer4-Layer6-Layer8...Layer50
and save 2 files
1.xcf
Layer1-Layer3-Layer5-Layer7...Layer49
2.xcf
Layer2-Layer4-Layer6-Layer8...Layer50
after i merge down Layer1 with Layer2, Layer3-Layer4, Layer5-Layer6....Layer49-Layer50 with your plugin interleave layers.
Is possible with your plugin interleave layers merge down alternate layers without create 2 images as on image attached?

I tried with deep-float.scm but merge only 2 layers, i don't know if there is an another script that do this automatically.

Thanks in advance and sorry for my request.

interleave-layers won't do it. Actually very simple to do in the python-fu console:

- make sure you have only one image open, then:

Code: Select all

image=gimp.image_list()[0]
for i in range(len(image.layers)/2):
  image.merge_down(layers[i],EXPAND_AS_NECESSARY)

Untested, but ready to bet the next round of beers

Otherwise post me an XCF image with some layer pairs (crop it to a small size, 20x20 or so), and I'll make a script.

For sure i'm inexpert about python-fu and i'm committing mistakes, can you help me? Thanks.
I've uploaded an image.xcf 20x20 that you have requested.

Sorry, not layers[i] but image.layers[i]... and you can put the for loop in one line:

Code: Select all

image=gimp.image_list()[0]
for i in range(len(image.layers)/2):image.merge_down(image.layers[i],EXPAND_AS_NECESSARY)

Executing it will list a bunch of layers ('<gimp.Layer 'Layer copy #31'>')... if you did it right these will be the bottom ones, which are left in the image.

PS: the beer is on me

As a script, with:
- single undo
- composiiton of names of the two source layers for the final layers

Menu entry is in <Image>/Image

Tried your script and works well, renamed all layers with script LayerGroups and merging down as i requested.
:oops:

is possible add to your script Opacity and modality of merging as on image?

Yes, but why didn't you ask earlier?

d4rkheart · **Joined:** Jul 21, 2012 **Posts:** 103

because i had not thought about these options :-(
but isn't a problem, i can change modality of all layers with a script that i've in my folder scripts.
