Tools for generating color gradient palettes and sha


Dependencies
=============
This driver depends on:

* `Adafruit CircuitPython <https://github.com/adafruit/circuitpython>`_

Please ensure all dependencies are available on the CircuitPython filesystem.
This is easily achieved by downloading
`the Adafruit library and driver bundle <https://circuitpython.org/libraries>`_
or individual libraries can be installed using
`circup <https://github.com/adafruit/circup>`_.Installing from PyPI
=====================


On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally `from
PyPI <https://pypi.org/project/Foamyguy-circuitpython-gradienthelper/>`_.
To install for current user:

.. code-block:: shell

    pip3 install Foamyguy-circuitpython-gradienthelper

To install system-wide (this may be required in some cases):

.. code-block:: shell

    sudo pip3 install Foamyguy-circuitpython-gradienthelper

To install in a virtual environment in your current project:

.. code-block:: shell

    mkdir project-name && cd project-name
    python3 -m venv .venv
    source .env/bin/activate
    pip3 install Foamyguy-circuitpython-gradienthelper

Installing to a Connected CircuitPython Device with Circup
==========================================================

Make sure that you have ``circup`` installed in your Python environment.
Install it with the following command if necessary:

.. code-block:: shell

    pip3 install circup

With ``circup`` installed and your CircuitPython device connected use the
following command to install:

.. code-block:: shell

    circup install gradienthelper

Or the following command to update an existing version:

.. code-block:: shell

    circup update

Usage Example
=============

.. code-block:: python

    from foamyguy_gradienthelper import (
        linear_gradient,
        polylinear_gradient,
        bezier_gradient,
    )

    def print_palette(palette):
        out_str = "["
        for color in palette:
            out_str = f"{out_str}{color:#0{8}x}, "
        out_str = out_str[:-2]
        out_str = f"{out_str}]"
        print(out_str)

    linear_colors = linear_gradient(0xFF0000, 0x0000FF, 10)
    print_palette(linear_colors)

    polylinear_colors = polylinear_gradient((0x00FF00, 0xFFFF00, 0x00FFFF), 30)
    print_palette(polylinear_colors)

    bezier_colors = bezier_gradient((0xFF00FF, 0x00FFFF, 0x00FF00), 100)
    print_palette(bezier_colors)
