# ofn3-mirror-layers

## Purpose

This script adds the selected layers in reverse order to the image.

## Usage

The script is started by the `Image > Mirror layers` menu. This menu is disabled if there are no selected layers or only one selected layer in the image (this script expects multiple layers as input).

### Parameters

- Method : Determines which layers are actually copied. Starting with five layers, `A,B,C,D,E` (from the bottom):
  - Swing (default) ignores both ends to produce `A,B,C,D,E,D,C,B`. This is what is needed for a back-and-forth animation, where the frames at both ends of the movement are only played once.
  - Symmetry is the actual symmetry copy: `A,B,C,D,E,E,D,C,B,A`.
  - Mirror uses a single frame in the middle: `A,B,C,D,E,D,C,B,A`
