Mass Layer Gimp Python Fu scripts

gistfile1.py

align multiple layers to the center of an image in gimp

layer = gimp.image_list()[0].layers[0]
image = gimp.image_list()[0]
for layer in gimp.image_list()[0].layers :
    x = (image.width - layer.width) / 2
    y = (image.height - layer.height) / 2
    layer.set_offsets(x, y)

gistfile2.py

Place each layer in an individual Layer Group

image = gimp.image_list()[0]
layerlist=gimp.image_list()[0].layers
for layer in  layerlist:
    if not pdb.gimp_item_is_group(layer):
        group = pdb.gimp_layer_group_new(image)
        group.name = layer.name+" group"
        image.add_layer(group, 0)
        newlayer = pdb.gimp_layer_copy(layer, 1)
        pdb.gimp_image_insert_layer(image, newlayer,group,0)
        image.remove_layer(layer)

gistfile3.py

create a border with the selection->path tool on all layers
I used this to with the erase tool set to 3px with a "hardness 50" brush to remove the burrs from 125 layers in about 30 seconds.


image = gimp.image_list()[0]
layerlist=gimp.image_list()[0].layers
for layer in  layerlist:
    if not pdb.gimp_item_is_group(layer):
        pdb.gimp_image_select_item(image,0,layer)
        pdb.plug_in_sel2path(image, layer)
        vector_name=pdb.gimp_path_list(image)[1][0]
        vec=pdb.gimp_image_get_vectors_by_name(image,vector_name)
        vec.name=layer.name+' selection'
        pdb.gimp_selection_clear(image)
        pdb.gimp_edit_stroke_vectors(layer, vec)
        pdb.gimp_path_delete(image, vec.name)

gistfile4.txt

in each layer group, create a few new layers for outlines, details, etc.

image = gimp.image_list()[0]
i=0
for layergroup in  gimp.image_list()[0].layers:
    if pdb.gimp_item_is_group(layergroup):
        i+=1
        layergroup.name = "group %s" % i
        layer = pdb.gimp_layer_new(image, image.width, image.height, 1, "outline %s" % i, 100.0, 0)
        pdb.gimp_image_insert_layer(image, layer, layergroup, 0)
        layer = pdb.gimp_layer_new(image, image.width, image.height, 1, "details %s" % i, 100.0, 0)
        pdb.gimp_image_insert_layer(image, layer, layergroup, 1)
        layer = pdb.gimp_layer_new(image, image.width, image.height, 1, "light and shadow %s" % i, 100.0, 14)
        pdb.gimp_image_insert_layer(image, layer, layergroup, 2)

gistfile5.txt

# in each layer group, rename the group name numerically.

image = gimp.image_list()[0]
i = 0
layerlist = gimp.image_list()[0].layers
for layergroup in layerlist:

    # each layergroup has 4 layers inside
    if pdb.gimp_item_is_group(layergroup):
        group=layerlist[i]
        group.name="group %s" % i
    i+=1
