GUI

Use the --cli2gui flag to launch a GUI

Alternatively, import into your project and use:

def generateHDColour(imageName, maxLen, trueColour=True, char="\u2584"):
	"""Iterate through image pixels to make a printable string

	Args:
		imageName (str): path of the image on the filesystem (relative of
		absolute)
		maxLen (int): maximum of width and height in chars
		trueColour (bool, optional): print in true colour. Defaults to True.
		char (str, optional): use this char for each pixel. Defaults to "\u2584".

	Returns:
		str: string to print
	"""

	"""Iterate through all of the pixels in an image and construct a printable
	string

	Args:
		imageName (str): path of the image on the filesystem (relative of
		absolute)

Documentation

A high-level overview of how the documentation is organized organized will help you know where to look for certain things:

• The Technical Reference documents APIs and other aspects of the machinery. This documentation describes how to use the classes and functions at a lower level and assume that you have a good high-level understanding of the software.

Building

This project uses https://github.com/FHPythonUtils/FHMake to automate most of the building. This command generates the documentation, updates the requirements.txt and builds the library artefacts

Note the functionality provided by fhmake can be approximated by the following

handsdown  --cleanup -o documentation/reference
poetry export -f requirements.txt --output requirements.txt
poetry export -f requirements.txt --with dev --output requirements_optional.txt
poetry build

fhmake audit can be run to perform additional checks

Testing

For testing with the version of python used by poetry use

poetry run pytest

Alternatively use tox to run tests over python 3.8 - 3.11

tox
