# Build tile configuration for ImageJ/Fiji Stitching plugin
# Author: David Young, 2017
"""Builds the tile grid layout for the ImageJ/Fiji Stitching plugin.

Attributes:
    OPTIONS_DIRECTIONALITY: direction of travel from one row to the next,
        where "uni" = unidirectional, "bi" = bidirectional
    OPTIONS_START_DIRECTION: starting direction of travel along the 1st
        row, where "right" = moving toward the right, "left" = moving
        toward the left
    TILE_CONFIG_FILE = default tile configuration name

Deprecated:
    This script is designed for the older Stitching plugin. Please see
    the :mod:`stitch.ij_bigstitch` module for the newer BigStitcher plugin.
