How to apply drop shadow or other filters to multiple layers? I created an animation with 100 layers, selected first layer, layer effects, drop shadow, after selected 2° layer, ctrl+f and it repeat drop shadow but with 100 and more layers is complicate.
Would be interesting a script or plugin that repeat last script, that i used, to all layers.
Thanks in advance.
Sorry for my bad english.

1 installing GAP
2 you may use Gmic, should have something similar to drop shadow in Lights and Shadows submenu
Just modify the gmic option for output (are close to the preview window ) in All layers before run the filter
3 There are 2 plugins
Gimpscript and BIMP that may automatize the use of most script and plugin

Thanks Photocomix.
- Gmic, works well but resize all layers.
- Bimp, i know that works well with images and not with layers :-(
- gap is installed but i don't remember how to save all frames and how to apply filters, i'm downloading a fencepost's tutorial about gap.
EDIT: i can't apply drop shadow with gap :-(
- gimpscript??

After running the G'MIC drop shadow filter for all layers, can't you just crop the image back to it's original dimensions?

For apply drop shadow filter to all layers i solved with LayerGroup script (layer groups-effects-drop shadow on layer group) and drop shadow 3d on gmic.
With gap is impossible apply every filters .scm.
@Wallace, thanks for your suggestion, yes i can but...i solved with drop shadow 3d, fortunately it doesn't resize layers.
Hope that i find a script/plugin that apply every filter to all layers.

Sorry for my bad english and thanks to everyone.

d4rkheart...Hey, I don't see one thing wrong with your English. I wish I could talk more than one language.

Ok, no problem. That would be a nice script to have.

You need saulgood's http://chiselapp.com/user/saulgoode/rep ... combine-bg

Make your drop shadow and move it to the bottom of the layer stack. Make sure any layers are visible that you want to have dropshadows. Hide layers where you don't want the shadow.

Be sure to refresh your scripts.

Then, Filters > Animation > Combine background. That puts a shadow under each visible layer.

If you want to have something to overlay layers, Filters > Animation > Overlay background

The bottom layer will be the drop shadow and will need to be deleted.

Adds command "Shadow All Layers" to "Filters->Light and Shadow" menu.

What if you have an object that moves say like a comic book character right arm waving.
Is it possible for a script to select the alpha for each visible right arm layer and then shadow? That way each shadow corresponds with an object and it's movement on the layer.
Or does the script do that already?

@ saulgoode, your script work well, on this animated png i applied your script...


@Molly, i don't know very well english and I worry to make mistakes
@Oregonian, thanks.
