Gimp-Batch

In menu: Tools -> Batch convert... 

For those who have trouble (or reluctance) to use Console or ImageMagic or you want to use GEGL filters (which the great BIMP does not yet support), this plug-in can make batch processing a little easier without needing to open files as a layers.

Plugin based on the idea of:

- TinTran Run Code on Visible Layers Script for GIMP   & here 

and 

- Saul Goode (Sg-Combine-Bg.scm - popular for animation, watermark or signature).


Be careful of:
- the possibility of losing metadata due to the possibility of using three types of files (bmp, jpg, png - which type opens, it saves it),
- size and type of overlay file (usually png with alpha channel - e.g .: for watermark or signature),
- it is possible to overwrite files (without warning) so try to select "Output Folder" empty,
- for Gegl Recommended for reading: Learn GEGL graph (Gimp Tutorials) by cli345 -> http://gimpchat.com/viewtopic.php?f=10&t=19463




Example custom code:

# for PDB:

pdb.gimp_image_scale(image, 250, 250)

(comment: scale the image using the default interpolation method. New image width=250   New image height=250) 
 
pdb.plug_in_autocrop(image ,layer)
 
(comment: remove empty borders from the image)

# for script-fu: 

pdb.script_fu_fuzzy_border(image ,layer ,(255,255,255),16,1,4,0,100,0,1) 

pdb.script_fu_old_photo(image, layer, 1, 20, 1,0,0)


# for GEGL:     

gegl_batch(image, layer, "cubism");gegl_batch(image, layer, "alien-map") <=or=> gegl_batch(image, layer, "cubism alien-map")

Basic syntax:

gegl_batch(image, layer, 'operations')

List of operations with parameters here.

 
# for Python:

pdb.python_fu_foggify(image, layer, "", (240,180,70), 1,100);

pdb.gimp_image_merge_visible_layers(image, 0)

 comment: Plugin Fog finishes working with two layers you need to combine them - so you need to add a procedure pdb.gimp_image_merge_visible_layers

 # for G'MIC

pdb.plug_in_gmic_qt( image, layer,1,0,'samj_Angoisse 1,5,0,5,100,2,4,1,250')



You can combine these operations into one command (separating them with a semicolon).

Here is an example of creating fancy seamless patterns: 

pdb.plug_in_gmic_qt( image, layer,1,0,'deform 60.7');pdb.plug_in_gmic_qt( image, layer,1,0,'samj_Angoisse 1,5,0,5,100,2,4,1,250');pdb.gimp_image_scale(image, 250, 250);gegl_batch(image, layer,'tile-seamless')

Sample result:

sample_lena.png


 sample_flower.png


 sample_dog.png
