Align Layers

This is a GIMP script that aligns the specified layer(s) against the specified image or another layer.

Alignment is performed horizontally (none, left, center, right) and/or vertically (none, top, center, bottom).

X- and Y-offsets can be specified as pixels, as percentages of image width/height or as percentages of the second layer width/height.

This script introduces a procedure named python-fu-align-layers. While aligning layers is already possible in GIMP, this script is intended to be used for automation purposes. Hence, there is no GUI associated with this procedure.

Usage

Example of centering the first layer against the image, both horizontally and vertically:

image = Gimp.get_images()[0]
layer_to_align = image.get_layers()[0]

procedure = Gimp.get_pdb().lookup_procedure('python-fu-align-layers')
config = procedure.create_config()
config.set_property('image', image)
config.set_core_object_array('drawables', [layer_to_align])
config.set_property('horizontal-align', 'center')
config.set_property('vertical-align', 'center')
procedure.run(config)

The parameters are explained in the GIMP procedure browser. The procedure name is python-fu-align-layers.

Installation

GIMP 3.0.0-RC1 or later is required.

For Linux, make sure you have at least Python 3.7 installed.

1. In GIMP, locate the folder containing GIMP plug-ins - open GIMP and go to Edit → Preferences → Folders → Plug-Ins.
2. Copy the align_layers folder inside one of the folders identified in step 1.
