Align Layer

This is a simple GIMP script that aligns a layer against another layer.

Alignment is performed both horizontally (none, left, center, right) and 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-layer. 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 second layer, both horizontally and vertically:

image = gimp.image_list()[0]
layer_to_align = image.layers[0]
reference_layer = image.layers[1]

pdb.python_fu_align_layer(image, layer_to_align, reference_layer, 2, 2, 0, 0, 0, 0)

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

Installation

GIMP 2.10 is required.

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

For Windows, make sure you have GIMP installed with support for Python scripting.

For Linux, make sure you use a GIMP installation bundled as Flatpak (which can be downloaded from the official GIMP page) or AppImage.

For macOS, make sure you have Python 2.7 installed.
