""" Converts pixel-art images into cross-stitch patterns.

	This tool assumes that 1px = 1 stitch.

	TODO:
		* Accept image name from command line.
		* Change characters to symbols for ease of reading.
		* Expand number of symbols.
		* Create image from symbolized pixels instead of just printing to screen.
		* Add grid lines and edge labels to image.
		* Add legend to image, based on the `symbols` dictionary.
		* Correspond hex colors to floss colors, where possible.
		* (Maybe) add stitch count for each color.
		* (Maybe) add GUI.
