Batcher - Batch Image Processing Plug-in for GIMP 3

[kaybee]

Hi there! I developed a batch image processing plug-in for GIMP 3.

Main features:

• Convert image files to any file format provided by GIMP and third-party plug-ins
  
• Export layers as separate images
  
• Export images opened in GIMP
  
• Batch-edit layers in an opened image
  
• Apply any GEGL filter or plug-in during batch processing (rename, scale, ...)
  
• Apply constraints to process only specific images/layers (matching a suffix, visible layers, ...)

Hello,

Beginner here: I haven't found out how to duplicate a layer. If anyone can ridicule me and tell me how simple it is...

Well, another beginner here and tried for hours using Batcher without success.

If you look at the attached Gimp 3 script-fu plugin (To try it unzip and put the macro-3 folder in your plugins folder  - registers in the Tools menu) these operations duplicate the image and add as a new active layer.
gimp-layer-new-from-visible followed by gimp-image-insert-layer
Trying those in Batcher and gimp-image-insert-layer crashes horribly.

If you have that little "macro" plugin installed, Batcher will recognise it   Add Procedure -> Add Custom Procedure -> Plugins and it works, making the new layer.  But for some reason the new layer is not the active layer and I can not find a way to make it active in Batcher. So not a lot of use for any following procedures.

Maybe if you give some information of your required workflow - new layer - some operation on that layer ... someone might come up with alternatives.

Hi, image/layer duplication is currently not possible in Batcher. I'll note this down as an enhancement in a future version. In the meantime, the workaround is to write a plug-in as Rich mentioned and add it as a custom action. You should then be able to manipulate the duplicate by selecting Layer Below (Background) or Layer Above (Foreground) (depending on the position the custom plug-in inserts the duplicate at) instead of Current Layer in subsequent actions.

In the future I plan to make a more generic (albeit more complex) approach where return values from one action could be used in another (e.g. add gimp-layer-new-from-visible and then gimp-image-insert-layer using the layer returned by the previous action).
