Okay. What is the alternative?

Mu own code does:

Code:

# make a copy of the layer, with an alpha channel
    mergedLayer=layer # so we return something anyway
    symLayer=layer.copy(True)
    image.add_layer(symLayer)
    symmetryFunction(image,layer,symLayer,symmetry)
    pdb.gimp_edit_clear(symLayer)
    pdb.gimp_selection_invert(image)
    pdb.gimp_edit_clear(layer)
    mergedLayer=image.merge_down(symLayer,EXPAND_AS_NECESSARY)

Where symmetryFunction is something like this (it basically transforms the top layer, and sets a selection so that the adequate parts can be
cleared)

Code:

def straightSymmetryCore(image,layer,symLayer,side):
    # Some arrays to avoid if/else, indexed by 'side'
    flipTypes=[ORIENTATION_VERTICAL,ORIENTATION_VERTICAL,ORIENTATION_HORIZONTAL,ORIENTATION_HORIZONTAL]
    x,y=layer.offsets
    w,h=layer.width,layer.height
    # The rects we delete in the flipped layer
    rects=[(x,y,w,h/2),(x,y+h-h/2,w,h/2),(x+w-w/2,y,w/2,h),(x,y,w/2,h)]
    
    # Rotate and flip as required
    symLayer.transform_flip_simple(flipTypes[side],True,0)
    pdb.gimp_image_select_rectangle(image, CHANNEL_OP_REPLACE,*rects[side])

The complete code is here. Note that:

• It's Python, not script-fu. if you have to learn a new language to write scripts, use Python. It's easier to learn, and can be used in many more places
  than Scheme/script-fu. If will also allow you to do more things.
  
• I use my scripts as test beds for new programming techniques. I hate verbosity, and repeating myself. It may make my code a bit obscure for the beginners. Simple Python is easier to read than simple script-fu.
